## 1. Introduction

At this stage, wireless communication technology is in a stage of rapid development, technology is constantly innovating, and people’s requirements for communication services are getting higher and higher, such as video-on-demand, live broadcast, Internet access, and multiparty video conferencing [1, 2]. The rapid development of various technologies such as computers and multimedia has promoted the improvement of processor architecture and buffering speed, and the improvement of microprocessor performance has increased rapidly. In the era of mobile Internet, sharing scenes relying on big data technology and mobile social media are affecting people’s media life. The scene experience is more individual and diverse, and it shows more open and inclusive characteristics through social connections. How to combine the wireless communication microprocessor with the mobile Internet and optimize the art design management mode is the focus of this article.Based on the intelligent art design management mode of wireless communication microprocessor and mobile Internet, it has the communication security ability of wireless communication, the data processing ability of the microprocessor, and the information transmission ability of the mobile Internet [3, 4]. This new type of art design management mode can combine the advantages of wireless communication, microprocessor, and mobile Internet, which greatly improves the art design ability and management ability, and has a great influence on students majoring in art design management.Ensuring ultrareliable and low-latency communication (URLLC) for 5G wireless networks and other networks is vital and is currently receiving great attention from academia and industry. Bennis studied the various contributing factors of URLLC and their inherent trade-offs [5]. It studies the problem of low-latency communication in wireless networks, which can improve the delay problem of microprocessors in wireless communication networks, but it is not comprehensive in terms of design management. In order to explore the performance of underwater wireless communication technology, Tian uses 80-m GaN-based blue micro-LEDs to achieve high-speed underwater optical wireless communication (UOWC) [6]. Its research on underwater optical wireless communication is very in-depth, but the combination with mobile Internet is not thorough enough. Smart devices bring people ubiquitous mobile access to the Internet, making the mobile Internet develop rapidly. Yang uses the mobile traffic data of China’s core metropolitan area 2G and 3G networks for more than a week to study mobile user behavior from three aspects: (1) data usage, (2) flow mode. and (3) application usage [7]. Although its research on mobile Internet is relatively in-depth, it is not fully integrated with wireless communication microprocessors. In order to study the routing protocol of the mobile Internet, Mukherjee has studied a new inter-domain routing protocol, which aims to meet the needs of the future mobile Internet [8]. He mainly studies mobile Internet routing protocols, which is of great help to the mobile Internet, but is insufficient in design management. The development of financial technology in the fields of mobile Internet, cloud computing, big data, search engines, and blockchain technology has significantly changed the financial industry. Chen used a comparative case study method to conduct a comparative analysis of the Industrial and Commercial Bank of China (ICBC) and Citibank [9]. His research is mainly based on the analysis of cases. If he can analyze how to combine wireless communication microprocessors and mobile Internet, it will be more in line with the purpose of this article. In order to study the reliability performance of embedded microprocessors, Filipe studied the impact of register file errors on the reliability of modern embedded microprocessors through fault injection and heavy ion experiments [10]. The focus of his research is embedded microprocessors. If wireless communication can be used for research, it would be more in line with the purpose of this article. In the field of microprocessors, many people are studying how to design a small microprocessor. Sato showed the design and experimental results of a fast single-flux quantum (RSFQ) bit serial microprocessor. The processor has a reduced embedded random access memory (RAM) and a minimum instruction set, called CORE e2h [11]. The microprocessor designed by his research involves insufficient wireless communication and needs to be combined with the Internet. According to an embodiment, Won provides a method for controlling congestion at an evolved node B (eNB) in a wireless communication network [12]. The research method can effectively solve the congestion problem. If the mobile Internet can be studied to design the art design management mode, it will be closer to the research of this article. All the above documents are mostly about wireless communications, microprocessors, and mobile Internet, but there are not many documents related to art design management. Next, this article needs to focus on the application of the combination of these three in art design management.The innovation of this paper is that it proposes the SOA service architecture of inspection system technology combining T2 microprocessor and mobile Internet, designs a system based on wireless communication microprocessor and mobile Internet, then calculates the inspection algorithm and its description, and then integrates the theoretical knowledge of art design management to construct an intelligent art design management mode based on wireless communication microprocessor and mobile Internet. The innovation of the experiment in this article is that the finite impulse response (FIR) filter test experiment and the end-to-end delay test experiment are designed to optimize the information transmission of the wireless communication processor and the delay of the mobile Internet.


## 2. Intelligent Art Design Management Method Based on Wireless Communication Microprocessor and Mobile Internet

### 2.1. Wireless Communication Microprocessor

#### 2.1.1. Communication Security

Generally speaking, to achieve secure communication [13–15], two requirements must be met. The first is to ensure that the legitimate receiving end can accurately restore the original information, and the second is to ensure that the sent information will not be stolen by any illegal eavesdropping end. The core idea of physical layer security is to use the randomness and uncertainty presented by the wireless channel affected by channel noise as a natural key element to realize the encryption and protection of communication data. It replaces the traditional key encryption technology and uses the encryption key derived from complex mathematical theories to achieve data encryption protection. Therefore, it can effectively interfere with the eavesdropping behavior of illegal users on the basis of not affecting the normal communication between the legal users and the two parties, thereby realizing the secure communication of the communication system. In the bottom line, physical layer security is to ensure the security of communication information transmission from the physical layer level, which is essentially different from traditional key encryption technology. Figure 1 shows the application field of wireless communication.Figure 1
Application of wireless communication.The establishment and analysis of the eavesdropping channel model [16] is the only way for wireless communication physical layer security research. This article will start from Shannon’s perfect security model and extend to Wyner eavesdropping channel model [17] and inspection eavesdropping channel model [18] to discuss the conditions and methods of secure communication.The basis of physical layer security is unconditional security in information theory, in the original model, as shown in Figure2.Figure 2
Shannon perfected the confidentiality model.However, due to the existence of the noise environment, the decoding accuracy of the legal receiver is greatly reduced. In order to make the decoding performance of B better than E and to achieve the above perfect confidentiality, Shannon introduced the “one time one secret” rule. Each piece of information corresponds to a key independent of it, shared by legitimate communication parties. In the figure, E is kept secret, A uses this key to process the original information, and B uses it to decrypt the received information.Considering the influence of noise in the actual communication environment, the eavesdropping channel model shown in Figure3 is proposed. This model differs from the ideal security model in two ways:
(1)
The legal sender A encodes the message W to obtain a code word Xn including n symbols, and sends it to the legal receiver B via the noise channel (main channel)(2)
The eavesdropper E receives a signal Zn in which the signal Yn received by B is interfered by noise from the eavesdropping channelFigure 3
Wyner eavesdropping channel model.MIMO communication system can have both transmit diversity and receive diversity, improve system efficiency and reliability, and is widely used in 3G and 4G wireless and mobile communication systems. Different from the previous two idealized models, the eavesdropping channel model and analysis in the inspection communication scenario are shown in Figure4.Figure 4
Inspection eavesdropping channel model.


#### 2.1.2. Inspection Technology

Inspection technology [19] uses multiple antenna space diversity gains (also called antenna diversity) on both the transmitting side and the receiving side. As the name suggests, MIMO systems are multiple input multiple output systems. However, if the sender is configured with multiple transmit antennas, and the receiver only configures a single receive antenna, the system will adopt a multiple-input multiple-output system, which is called a multiple-input single-output (MISO) system [20]. A system with multiple receiving antennas at the end is called a single-input multiple-output (SIMO) system [21].In an inspection system, there are multiple pairs of transmitting antennas and receiving antennas, and multiple different information transmission channels are formed between them. Among these many paths, the source information can choose any path to reach the destination. As long as the fading ratio of one of the paths is small, the information can reach the destination smoothly to complete the communication. Therefore, the more transceiver antenna pairs there are in the system, the greater the diversity of the received signal, the greater the gain obtained, and the better the performance of the system.


#### 2.1.3. Microprocessor

The T2 processor [22] is a number of sub-auxiliary processors. Each processor core includes two groups of 8 threads. Fine-grained multithreading is used in each group, and multithreading is used between groups at the same time. In a loop, each thread group selects a thread and issues a command. In other words, T2 can implement a multithreaded dual-start structure and can only execute instructions from two threads at most. In addition, there are integer pipelines and floating-point pipelines in the kernel, and each thread can perform floating-point operations in a loop, and all kinds of threads are completely pipelined.(1) RapidIO Protocol. The RapidIO interface bus protocol [23] adopts a three-layer architecture. This layered structure has strong flexibility. Modifying the protocol specifications of one layer will not affect the other layers. The logic layer defines all protocols and packet formats of the RapidIO bus. The function of this layer is mainly to enable some endpoint devices to use the important information it carries to complete and implement transaction work. For example, initiating and completing transactions, including multiple operations and transactions in the logic layer, these main transactions and operations include messages, doorbells, and I/O operations.RapidIO transaction operation is realized by request and response. In terms of communication between systems, data packets are the most basic unit, similar to the words people need to communicate. The communication process is also similar to the communication process between humans. Initially, the sending device needs to initiate a dialogue. After the request transaction is received, the purpose will send a response transaction, which is mainly used to explain whether the request transaction has been processed or encountered an error. And all the related transaction types and all bit fields of RapidIO are encapsulated in the packet. RapidIO endpoint interconnection often depends on some media, such as intermediary or exchange structure. In addition, there are many functions and functions of control symbols, such as confirming packets and maintaining some common functions. In addition, under normal circumstances, it is mainly used to control the transaction flow and flow information of the interconnection between the RapidIO physical layers.All operation transactions in the RapidIO bus are encapsulated in packets, and the transmission method is based on request responses. Therefore, the corresponding packets are divided into request packets and response packets. The main content of the packet contains information about all layers, for example, some load data that can be used to select, the information in the header of the packet, and the CRC check code. The packet length is an integer multiple of 32 bits, which is consistent with the width of the internal data path. The length of the packet is defined by the joint agreement as an odd multiple of 16 bits, we need to add 16-bit padding to the end of the packet, and the value is0×0000. In order to reduce the transmission delay and simplify the hardware implementation complexity, the payload data length of the packet does not exceed 256 bytes.(2) Key Performance Indicators of the Storage System. From the perspective of architecture, the performance of the storage system is determined by the storage hierarchy and related control strategies, and the continuous development of storage architecture and efficient control strategies have greatly improved the performance of the storage system. Usually there are two key indicators to measure the performance of a storage system, instant delay and effective bandwidth.Latency is the total number of clock cycles consumed in the whole process from the time the processor sends out a memory access request and is calculated until the required data is returned. Due to the lack of on-chip cache, the existence of the system bus or memory access path may be occupied by other devices, and the latency of each access is different, so the latency is usually defined as the average of the processor’s memory access latency value.The effective bandwidth refers to the average total number of bytes of data actually used by the application program to read and write to the memory per unit time. It reflects the effective data transfer rate between the processor core and the storage system and is usually called the throughput rate. The effective bandwidth is not only affected by the operating frequency of the system bus and the way of data interaction, but also closely related to the on-chip storage control strategy.(3) Key Technologies of Microprocessors.

Von Neumann Structure and Harvard Structure. In the division of memory structure, microprocessors can be divided into von Neumann structure [24] and Harvard structure [20]. The von Neumann structure is a memory structure that combines instruction memory and data memory. In other words, commands and data are stored in the same memory and share the data bus, so the von Neumann structure cannot be used to read commands and data at the same time. The Harvard structure is characterized by a memory structure that separates commands and data. Program memory and data memory are completely independent in space. The Harvard architecture includes the address bus and the data bus of the program memory and at least two sets of the address bus and the data bus of the data memory. The Harvard structure is a parallel structure. In one clock cycle, instructions and data can be obtained at the same time, and the next instruction can be read after the current instruction is executed. Therefore, the efficiency of the processor using the Harvard structure will be improved(2)
CISC and RISC. The instruction set architecture of the microprocessor is divided into complex instruction set (CISC) [25] and reduced instruction set (RISC) [26]Early computers adopted the CISC instruction set architecture. In order to facilitate software programming and improve the execution speed of the program, designers continue to increase instructions and multiple addressing methods that can realize complex functions, so that fewer instructions are required to complete a task, and it is convenient for the design of the compiler. However, the unfixed instruction format and diversified addressing methods make the hardware more and more complicated, and the cost of the CPU is also higher and higher.In order to make the processor run faster and more efficient, and the hardware structure is more reasonable and simple, RISC is developed on the basis of CISC. The design idea of the RISC processor is to take advantage of the fast execution speed of simple instructions, reduce the complexity of computer instructions, and retain only those with simple functions and high frequency of use. And in the simple instructions that can be executed in one clock cycle, the previous complex instructions are completed with a group of simple instructions [27, 28].Compared with CISC, RISC has the characteristics of fixed instruction length, large use of registers, fewer addressing modes and instruction formats, etc., because most instructions in the RISC instruction set only need one clock cycle to complete. So the running speed of RISC processor can be greatly improved, and it is convenient for pipeline design.


### 2.2. Mobile Internet

#### 2.2.1. Definition of the Concept of Mobile Internet

Mobile Internet is a new network form formed by the integration of mobile communication and the Internet. It provides users with more mobile functions, deepens the network and service system, and enriches people’s production and life, and diversity can improve convenience. A basic communication network is defined from a technical perspective, which can provide voice, data, and multimedia services at the same time with an IP data network as the core. From a terminal point of view, mobile terminals such as mobile phones, laptops, and tablets; Internet services; and mobile communication services can be used (as shown in Figure5).Figure 5
Mobile Internet architecture.Mobile Internet security risks include all levels of security, such as terminal security risks, network security risks, and application security risks. Criminals can use illegal operations and unauthorized access through terminal systems [29, 30]. The data sent through the mobile communication network can be easily intercepted and tampered with. The security of the mobile Internet requires the establishment of a comprehensive security management system.


#### 2.2.2. The Characteristics of the Mobile Internet

The characteristics of the mobile Internet can be summarized as follows:(1)
The terminal is convenient to carry: generally speaking, the mobile terminal is small and light, so the time used by the user must be much longer than that of a fixed computer. Obviously, using mobile devices has irreplaceable advantages over fixed computers to surf the Internet. Daily communication and obtaining information are more convenient and quicker than fixed computers(2)
High information privacy: compared with fixed computers, the privacy of information carried by mobile terminals is more important. The information carried by the mobile terminal is generally shared in real time, such as location information, address book information, short message information, and payment information. This determines that the mobile terminal information should be highly private. Traditional Internet information is open and transparent, and fixed computer systems can share user information arbitrarily, but mobile Internet users are definitely not willing to do so(3)
Lightweight applications: mobile Internet applications are relatively simple and straightforward, such as making phone calls, sending text messages, taking photos, and sending videos, which are all basic needs of daily life and work, requiring convenience and speed. Moreover, the lightweight and simplification of the mobile terminal itself cannot achieve the operation of a complex input terminal similar to a keyboard on a fixed computer. Users often only have simple input and output needs and do not require large, complex, and long-term processing and calculations. Therefore, mobile application software is relatively lightweight, and complex processing operations are generally in the cloud


#### 2.2.3. Introduction to SOA

SOA (service-oriented architecture) is a set of system distributed software solutions and environments, including an operating environment, a program model, an architectural style, engineering methods, and related technologies.The biggest benefit of SOA is that it provides a comprehensive environment of service concentration points through rapid business changes and business optimization and close communication between the business layer and the model. In addition, based on a loosely coupled system, service changes are localized.


### 2.3. Art Design Management

Design management goes beyond comprehensive new areas including industrial design and business management. Design management refers to defining design problems, finding suitable designers, and allowing designers to solve design problems in a timely manner within budget. And art design management is a fusion discipline based on design management combined with art design. Figure6 shows the framework of the design management theory system.Figure 6
Design management theory system architecture.The basic characteristics of design management can be summarized as three points: (1) attach great importance to design, (2) understand design correctly, and (3) introduce design gradually.Attaching great importance to design is the prerequisite for all design management. Nowadays, as design is more and more well-known by people and more and more operators are introduced into the business activities of enterprises, the importance of design seems to have reached a consensus. But when we further examine the manager’s attitude towards design, we will find that design is still not in its proper place in their minds. In most business activities, we can find that design is only seen as a dispensable embellishment. To truly realize the importance of design, managers must do the following:(1)
Using design as a management tool. The purpose of the design is to provide consumers with high-quality products. In the design process, the design organization often needs to establish product design standards to control and test whether the designed product actually meets the requirements of consumers. Therefore, this activity also encourages companies to easily establish a set of high-quality product standards in the design, production, and management links with the help of design to promote various departments and plays an extremely important role in improving the management efficiency and economic efficiency of the enterprise. On the contrary, without the driving effect of design, such a standard would be difficult to establish. Therefore, taking design as a management tool is an important way to effectively promote the establishment of product standards for enterprises and improve their operating efficiency(2)
Letting the design enter the high-level agenda. To make enterprises attach great importance to design, the most important thing is that the senior leaders of the enterprise should pay attention to design. In some enterprises, because the design does not get the attention of the managers, especially the senior managers, it is easy to cause each department to work independently. The design lacks a unified standard, which makes the enterprise unable to reach an externally consistent image. What is more serious is that because the company has no dedicated person responsible for the design, it leads to confusion in design decisions. To solve these problems, it is necessary to let the design enter the agenda of the senior leaders of the enterprise and make the design truly become the daily concern of the enterprise leaders(3)
Making the design policy penetrate into all levels of the enterprise. Innovation is the driving force for the development of an enterprise. Only by continuous innovation can an enterprise remain vigorous and undefeated in the fierce market competition. But enterprise innovation cannot rely on a few people in the enterprise; it must rely on every employee in every functional department in the enterprise. The design must obtain support from all aspects of the company, and the most important thing is to implement the company’s design policy to the end


### 2.4. Inspection Detection Algorithm

The spatial multiplexing inspection system can transmit data at a higher rate. For an inspection system with a number of antennas, letG denotes a channel matrix, where each element denotes the channel gain between the xth transmit antenna and the yth receive antenna, where
(1)x=1,2,⋯,KSa,(2)y=1,2,⋯,KRa.Denoting the spatially multiplexed user data and the corresponding received signal as(3)a=a1,a2,⋯,aKSaS,(4)b=b1,b2,⋯,bKRaS.Among them,ax and bx, respectively, represent the transmit signal of the first transmit antenna and the receive signal of the first receive antenna. Letting cy denotes the additive white Gaussian noise of the yth receiving antenna, with a variance of γc2. Letting gx denotes the xth column vector of the channel matrix G, and then the inspection system of KSa×KRa can be expressed as
(5)b=Ga+c=g1a1+g2a2+⋯+gKSaaKSa+c.Among them(6)c=c1,c2,⋯,cKRaS.In an inspection system, what each receiving antenna receives is a superposition of the signals sent by each transmitting antenna. Linear equalization is the received signalband the weighting matrix W, which is
(7)a~=a~1,a~2,⋯,a~Ksa=Wb.The weighting matrix of ZF equalization is(8)WZF=GGG−1GG.Then the corresponding transmitted signal obtained by equalizing the received signal is(9)a~ZF=WZFb=a+GGG−1GGc=a+c~ZF.Among them(10)c~ZF=WZFc=GGG−1GGc.Since the bit error rate is closely related to the power ofc~ZF, using singular value decomposition, the noise power after detection is
(11)c~ZF22=VΣ−1UGc2.For the unitary matrixE satisfies
(12)Ea2=aGEGEa=a2.Therefore, the expected value of noise power is(13)Qc~ZF22=γc2SrΣ−2=∑x=1KSaγc2γa2.MMSE can maximize the SINR after detection, so that its weighting matrix is(14)WMMSE=GGG+γc2X−1GG.The receiver needs noise statistics 1. Using the MMSE weighting matrix of the formula, the following relationship can be obtained:(15)a~MMSE=WMMSEb=a~+c~MMSE.Among them(16)c~MMSE=GGG+γc2X−1GGc.Using singular value decomposition, the noise power after detection is(17)c~MMSE=VΣ2VG+γc2X−1VΣUGc2.According to the fact that the unitary matrix does not change the norm of the vector, i.e.,(18)Va2=a2.Its expected value is(19)Qc~MMSE22=∑x=1KSaγc2γa+γc2γa−2=∑x=1KSaγc2γa2γa+γc2.If the condition number of the channel matrix is very large, that is, the smallest singular value is very small, the effect of noise enhancement in the linear filtering process will be more important. For ZF and MMSE linear detectors, the effect of noise enhancement caused by the smallest singular value is different.(20)Qc~ZF22=∑x=1KSaγc2γmin2≈γc2γmin2,ZF,(21)Qc~MMSE22=∑x=1KSaγc2γa2γa+γc2≈γc2γmin2γmin2+γc2,MMSE.Among them(22)γmin2=minγ12,γ22,⋯,γKSa2.


## 2.1. Wireless Communication Microprocessor

### 2.1.1. Communication Security

Generally speaking, to achieve secure communication [13–15], two requirements must be met. The first is to ensure that the legitimate receiving end can accurately restore the original information, and the second is to ensure that the sent information will not be stolen by any illegal eavesdropping end. The core idea of physical layer security is to use the randomness and uncertainty presented by the wireless channel affected by channel noise as a natural key element to realize the encryption and protection of communication data.

Inspection technology [19] uses multiple antenna space diversity gains (also called antenna diversity) on both the transmitting side and the receiving side.

As long as the fading ratio of one of the paths is small, the information can reach the destination smoothly to complete the communication. Therefore, the more transceiver antenna pairs there are in the system, the greater the diversity of the received signal, the greater the gain obtained, and the better the performance of the system.

Von Neumann Structure and Harvard Structure. In the division of memory structure, microprocessors can be divided into von Neumann structure [24] and Harvard structure [20]. The von Neumann structure is a memory structure that combines instruction memory and data memory. In other words, commands and data are stored in the same memory and share the data bus, so the von Neumann structure cannot be used to read commands and data at the same time. The Harvard structure is characterized by a memory structure that separates commands and data. Program memory and data memory are completely independent in space. The Harvard architecture includes the address bus and the data bus of the program memory and at least two sets of the address bus and the data bus of the data memory. The Harvard structure is a parallel structure. In one clock cycle, instructions and data can be obtained at the same time, and the next instruction can be read after the current instruction is executed. Therefore, the efficiency of the processor using the Harvard structure will be improved(2)
CISC and RISC. The instruction set architecture of the microprocessor is divided into complex instruction set (CISC) [25] and reduced instruction set (RISC) [26]Early computers adopted the CISC instruction set architecture. In order to facilitate software programming and improve the execution speed of the program, designers continue to increase instructions and multiple addressing methods that can realize complex functions, so that fewer instructions are required to complete a task, and it is convenient for the design of the compiler. However, the unfixed instruction format and diversified addressing methods make the hardware more and more complicated, and the cost of the CPU is also higher and higher.In order to make the processor run faster and more efficient, and the hardware structure is more reasonable and simple, RISC is developed on the basis of CISC. The design idea of the RISC processor is to take advantage of the fast execution speed of simple instructions, reduce the complexity of computer instructions, and retain only those with simple functions and high frequency of use. And in the simple instructions that can be executed in one clock cycle, the previous complex instructions are completed with a group of simple instructions [27, 28].Compared with CISC, RISC has the characteristics of fixed instruction length, large use of registers, fewer addressing modes and instruction formats, etc., because most instructions in the RISC instruction set only need one clock cycle to complete. So the running speed of RISC processor can be greatly improved, and it is convenient for pipeline design.


## 2.1.1. Communication Security

Generally speaking, to achieve secure communication [13–15], two requirements must be met. The first is to ensure that the legitimate receiving end can accurately restore the original information, and the second is to ensure that the sent information will not be stolen by any illegal eavesdropping end. The core idea of physical layer security is to use the randomness and uncertainty presented by the wireless channel affected by channel noise as a natural key element to realize the encryption and protection of communication data. It replaces the traditional key encryption technology and uses the encryption key derived from complex mathematical theories to achieve data encryption protection. Therefore, it can effectively interfere with the eavesdropping behavior of illegal users on the basis of not affecting the normal communication between the legal users and the two parties, thereby realizing the secure communication of the communication system. In the bottom line, physical layer security is to ensure the security of communication information transmission from the physical layer level, which is essentially different from traditional key encryption technology. Figure 1 shows the application field of wireless communication.Figure 1
Application of wireless communication.The establishment and analysis of the eavesdropping channel model [16] is the only way for wireless communication physical layer security research. This article will start from Shannon’s perfect security model and extend to Wyner eavesdropping channel model [17] and inspection eavesdropping channel model [18] to discuss the conditions and methods of secure communication.The basis of physical layer security is unconditional security in information theory, in the original model, as shown in Figure2.Figure 2
Shannon perfected the confidentiality model.However, due to the existence of the noise environment, the decoding accuracy of the legal receiver is greatly reduced. In order to make the decoding performance of B better than E and to achieve the above perfect confidentiality, Shannon introduced the “one time one secret” rule. Each piece of information corresponds to a key independent of it, shared by legitimate communication parties. In the figure, E is kept secret, A uses this key to process the original information, and B uses it to decrypt the received information.Considering the influence of noise in the actual communication environment, the eavesdropping channel model shown in Figure3 is proposed. This model differs from the ideal security model in two ways:
(1)
The legal sender A encodes the message W to obtain a code word Xn including n symbols, and sends it to the legal receiver B via the noise channel (main channel)(2)
The eavesdropper E receives a signal Zn in which the signal Yn received by B is interfered by noise from the eavesdropping channelFigure 3
Wyner eavesdropping channel model.MIMO communication system can have both transmit diversity and receive diversity, improve system efficiency and reliability, and is widely used in 3G and 4G wireless and mobile communication systems. Different from the previous two idealized models, the eavesdropping channel model and analysis in the inspection communication scenario are shown in Figure4.Figure 4
Inspection eavesdropping channel model.


## 2.1.2. Inspection Technology

Inspection technology [19] uses multiple antenna space diversity gains (also called antenna diversity) on both the transmitting side and the receiving side. As the name suggests, MIMO systems are multiple input multiple output systems. However, if the sender is configured with multiple transmit antennas, and the receiver only configures a single receive antenna, the system will adopt a multiple-input multiple-output system, which is called a multiple-input single-output (MISO) system [20]. A system with multiple receiving antennas at the end is called a single-input multiple-output (SIMO) system [21].In an inspection system, there are multiple pairs of transmitting antennas and receiving antennas, and multiple different information transmission channels are formed between them. Among these many paths, the source information can choose any path to reach the destination. As long as the fading ratio of one of the paths is small, the information can reach the destination smoothly to complete the communication. Therefore, the more transceiver antenna pairs there are in the system, the greater the diversity of the received signal, the greater the gain obtained, and the better the performance of the system.


## 2.1.3. Microprocessor

The T2 processor [22] is a number of sub-auxiliary processors. Each processor core includes two groups of 8 threads. Fine-grained multithreading is used in each group, and multithreading is used between groups at the same time. In a loop, each thread group selects a thread and issues a command. In other words, T2 can implement a multithreaded dual-start structure and can only execute instructions from two threads at most. In addition, there are integer pipelines and floating-point pipelines in the kernel, and each thread can perform floating-point operations in a loop, and all kinds of threads are completely pipelined.(1) RapidIO Protocol. The RapidIO interface bus protocol [23] adopts a three-layer architecture. This layered structure has strong flexibility. Modifying the protocol specifications of one layer will not affect the other layers. The logic layer defines all protocols and packet formats of the RapidIO bus. The function of this layer is mainly to enable some endpoint devices to use the important information it carries to complete and implement transaction work. For example, initiating and completing transactions, including multiple operations and transactions in the logic layer, these main transactions and operations include messages, doorbells, and I/O operations.RapidIO transaction operation is realized by request and response. In terms of communication between systems, data packets are the most basic unit, similar to the words people need to communicate. The communication process is also similar to the communication process between humans. Initially, the sending device needs to initiate a dialogue. After the request transaction is received, the purpose will send a response transaction, which is mainly used to explain whether the request transaction has been processed or encountered an error. And all the related transaction types and all bit fields of RapidIO are encapsulated in the packet. RapidIO endpoint interconnection often depends on some media, such as intermediary or exchange structure. In addition, there are many functions and functions of control symbols, such as confirming packets and maintaining some common functions. In addition, under normal circumstances, it is mainly used to control the transaction flow and flow information of the interconnection between the RapidIO physical layers.All operation transactions in the RapidIO bus are encapsulated in packets, and the transmission method is based on request responses. Therefore, the corresponding packets are divided into request packets and response packets. The main content of the packet contains information about all layers, for example, some load data that can be used to select, the information in the header of the packet, and the CRC check code. The packet length is an integer multiple of 32 bits, which is consistent with the width of the internal data path. The length of the packet is defined by the joint agreement as an odd multiple of 16 bits, we need to add 16-bit padding to the end of the packet, and the value is0×0000. In order to reduce the transmission delay and simplify the hardware implementation complexity, the payload data length of the packet does not exceed 256 bytes.(2) Key Performance Indicators of the Storage System. From the perspective of architecture, the performance of the storage system is determined by the storage hierarchy and related control strategies, and the continuous development of storage architecture and efficient control strategies have greatly improved the performance of the storage system. Usually there are two key indicators to measure the performance of a storage system, instant delay and effective bandwidth.Latency is the total number of clock cycles consumed in the whole process from the time the processor sends out a memory access request and is calculated until the required data is returned. Due to the lack of on-chip cache, the existence of the system bus or memory access path may be occupied by other devices, and the latency of each access is different, so the latency is usually defined as the average of the processor’s memory access latency value.The effective bandwidth refers to the average total number of bytes of data actually used by the application program to read and write to the memory per unit time. It reflects the effective data transfer rate between the processor core and the storage system and is usually called the throughput rate. The effective bandwidth is not only affected by the operating frequency of the system bus and the way of data interaction, but also closely related to the on-chip storage control strategy.(3) Key Technologies of Microprocessors.

Von Neumann Structure and Harvard Structure. In the division of memory structure, microprocessors can be divided into von Neumann structure [24] and Harvard structure [20]. The von Neumann structure is a memory structure that combines instruction memory and data memory. In other words, commands and data are stored in the same memory and share the data bus, so the von Neumann structure cannot be used to read commands and data at the same time. The Harvard structure is characterized by a memory structure that separates commands and data. Program memory and data memory are completely independent in space. The Harvard architecture includes the address bus and the data bus of the program memory and at least two sets of the address bus and the data bus of the data memory. The Harvard structure is a parallel structure. In one clock cycle, instructions and data can be obtained at the same time, and the next instruction can be read after the current instruction is executed. Therefore, the efficiency of the processor using the Harvard structure will be improved(2)
CISC and RISC. The instruction set architecture of the microprocessor is divided into complex instruction set (CISC) [25] and reduced instruction set (RISC) [26]Early computers adopted the CISC instruction set architecture. In order to facilitate software programming and improve the execution speed of the program, designers continue to increase instructions and multiple addressing methods that can realize complex functions, so that fewer instructions are required to complete a task, and it is convenient for the design of the compiler. However, the unfixed instruction format and diversified addressing methods make the hardware more and more complicated, and the cost of the CPU is also higher and higher.In order to make the processor run faster and more efficient, and the hardware structure is more reasonable and simple, RISC is developed on the basis of CISC. The design idea of the RISC processor is to take advantage of the fast execution speed of simple instructions, reduce the complexity of computer instructions, and retain only those with simple functions and high frequency of use. And in the simple instructions that can be executed in one clock cycle, the previous complex instructions are completed with a group of simple instructions [27, 28].Compared with CISC, RISC has the characteristics of fixed instruction length, large use of registers, fewer addressing modes and instruction formats, etc., because most instructions in the RISC instruction set only need one clock cycle to complete. So the running speed of RISC processor can be greatly improved, and it is convenient for pipeline design.


## 2.2. Mobile Internet

### 2.2.1. Definition of the Concept of Mobile Internet

Mobile Internet is a new network form formed by the integration of mobile communication and the Internet. It provides users with more mobile functions, deepens the network and service system, and enriches people’s production and life, and diversity can improve convenience. A basic communication network is defined from a technical perspective, which can provide voice, data, and multimedia services at the same time with an IP data network as the core. From a terminal point of view, mobile terminals such as mobile phones, laptops, and tablets; Internet services; and mobile communication services can be used (as shown in Figure5).Figure 5
Mobile Internet architecture.Mobile Internet security risks include all levels of security, such as terminal security risks, network security risks, and application security risks. Criminals can use illegal operations and unauthorized access through terminal systems [29, 30]. The data sent through the mobile communication network can be easily intercepted and tampered with. The security of the mobile Internet requires the establishment of a comprehensive security management system.


### 2.2.2. The Characteristics of the Mobile Internet

The characteristics of the mobile Internet can be summarized as follows:(1)
The terminal is convenient to carry: generally speaking, the mobile terminal is small and light, so the time used by the user must be much longer than that of a fixed computer. Obviously, using mobile devices has irreplaceable advantages over fixed computers to surf the Internet. Daily communication and obtaining information are more convenient and quicker than fixed computers(2)
High information privacy: compared with fixed computers, the privacy of information carried by mobile terminals is more important. The information carried by the mobile terminal is generally shared in real time, such as location information, address book information, short message information, and payment information. This determines that the mobile terminal information should be highly private. Traditional Internet information is open and transparent, and fixed computer systems can share user information arbitrarily, but mobile Internet users are definitely not willing to do so(3)
Lightweight applications: mobile Internet applications are relatively simple and straightforward, such as making phone calls, sending text messages, taking photos, and sending videos, which are all basic needs of daily life and work, requiring convenience and speed. Moreover, the lightweight and simplification of the mobile terminal itself cannot achieve the operation of a complex input terminal similar to a keyboard on a fixed computer. Users often only have simple input and output needs and do not require large, complex, and long-term processing and calculations. Therefore, mobile application software is relatively lightweight, and complex processing operations are generally in the cloud


### 2.2.3. Introduction to SOA

SOA (service-oriented architecture) is a set of system distributed software solutions and environments, including an operating environment, a program model, an architectural style, engineering methods, and related technologies.The biggest benefit of SOA is that it provides a comprehensive environment of service concentration points through rapid business changes and business optimization and close communication between the business layer and the model. In addition, based on a loosely coupled system, service changes are localized.

## 2.3. Art Design Management

Design management goes beyond comprehensive new areas including industrial design and business management. Design management refers to defining design problems, finding suitable designers, and allowing designers to solve design problems in a timely manner within budget. And art design management is a fusion discipline based on design management combined with art design. Figure6 shows the framework of the design management theory system.Figure 6
Design management theory system architecture.The basic characteristics of design management can be summarized as three points: (1) attach great importance to design, (2) understand design correctly, and (3) introduce design gradually.Attaching great importance to design is the prerequisite for all design management. Nowadays, as design is more and more well-known by people and more and more operators are introduced into the business activities of enterprises, the importance of design seems to have reached a consensus. But when we further examine the manager’s attitude towards design, we will find that design is still not in its proper place in their minds. In most business activities, we can find that design is only seen as a dispensable embellishment. To truly realize the importance of design, managers must do the following:(1)
Using design as a management tool. The purpose of the design is to provide consumers with high-quality products. In the design process, the design organization often needs to establish product design standards to control and test whether the designed product actually meets the requirements of consumers. Therefore, this activity also encourages companies to easily establish a set of high-quality product standards in the design, production, and management links with the help of design to promote various departments and plays an extremely important role in improving the management efficiency and economic efficiency of the enterprise. On the contrary, without the driving effect of design, such a standard would be difficult to establish. Therefore, taking design as a management tool is an important way to effectively promote the establishment of product standards for enterprises and improve their operating efficiency(2)
Letting the design enter the high-level agenda. To make enterprises attach great importance to design, the most important thing is that the senior leaders of the enterprise should pay attention to design. In some enterprises, because the design does not get the attention of the managers, especially the senior managers, it is easy to cause each department to work independently. The design lacks a unified standard, which makes the enterprise unable to reach an externally consistent image. What is more serious is that because the company has no dedicated person responsible for the design, it leads to confusion in design decisions. To solve these problems, it is necessary to let the design enter the agenda of the senior leaders of the enterprise and make the design truly become the daily concern of the enterprise leaders(3)
Making the design policy penetrate into all levels of the enterprise. Innovation is the driving force for the development of an enterprise. Only by continuous innovation can an enterprise remain vigorous and undefeated in the fierce market competition. But enterprise innovation cannot rely on a few people in the enterprise; it must rely on every employee in every functional department in the enterprise. The design must obtain support from all aspects of the company, and the most important thing is to implement the company’s design policy to the end


## 2.4. Inspection Detection Algorithm

The spatial multiplexing inspection system can transmit data at a higher rate. For an inspection system with a number of antennas, letG denotes a channel matrix, where each element denotes the channel gain between the xth transmit antenna and the yth receive antenna, where
(1)x=1,2,⋯,KSa,(2)y=1,2,⋯,KRa.Denoting the spatially multiplexed user data and the corresponding received signal as(3)a=a1,a2,⋯,aKSaS,(4)b=b1,b2,⋯,bKRaS.Among them,ax and bx, respectively, represent the transmit signal of the first transmit antenna and the receive signal of the first receive antenna. Letting cy denotes the additive white Gaussian noise of the yth receiving antenna, with a variance of γc2. Letting gx denotes the xth column vector of the channel matrix G, and then the inspection system of KSa×KRa can be expressed as
(5)b=Ga+c=g1a1+g2a2+⋯+gKSaaKSa+c.Among them(6)c=c1,c2,⋯,cKRaS.In an inspection system, what each receiving antenna receives is a superposition of the signals sent by each transmitting antenna. Linear equalization is the received signalband the weighting matrix W, which is
(7)a~=a~1,a~2,⋯,a~Ksa=Wb.The weighting matrix of ZF equalization is(8)WZF=GGG−1GG.Then the corresponding transmitted signal obtained by equalizing the received signal is(9)a~ZF=WZFb=a+GGG−1GGc=a+c~ZF.Among them(10)c~ZF=WZFc=GGG−1GGc.Since the bit error rate is closely related to the power ofc~ZF, using singular value decomposition, the noise power after detection is
(11)c~ZF22=VΣ−1UGc2.For the unitary matrixE satisfies
(12)Ea2=aGEGEa=a2.Therefore, the expected value of noise power is(13)Qc~ZF22=γc2SrΣ−2=∑x=1KSaγc2γa2.MMSE can maximize the SINR after detection, so that its weighting matrix is(14)WMMSE=GGG+γc2X−1GG.The receiver needs noise statistics 1. Using the MMSE weighting matrix of the formula, the following relationship can be obtained:(15)a~MMSE=WMMSEb=a~+c~MMSE.Among them(16)c~MMSE=GGG+γc2X−1GGc.Using singular value decomposition, the noise power after detection is(17)c~MMSE=VΣ2VG+γc2X−1VΣUGc2.According to the fact that the unitary matrix does not change the norm of the vector, i.e.,(18)Va2=a2.Its expected value is(19)Qc~MMSE22=∑x=1KSaγc2γa+γc2γa−2=∑x=1KSaγc2γa2γa+γc2.If the condition number of the channel matrix is very large, that is, the smallest singular value is very small, the effect of noise enhancement in the linear filtering process will be more important. For ZF and MMSE linear detectors, the effect of noise enhancement caused by the smallest singular value is different.(20)Qc~ZF22=∑x=1KSaγc2γmin2≈γc2γmin2,ZF,(21)Qc~MMSE22=∑x=1KSaγc2γa2γa+γc2≈γc2γmin2γmin2+γc2,MMSE.Among them(22)γmin2=minγ12,γ22,⋯,γKSa2.


## 3. Wireless Communication Microprocessor and Mobile Internet Test Experiment

### 3.1. Finite Impulse Response (FIR) Filter Test Experiment

The encoding of the processor instruction set is a crucial part of the processor. The difference between different instructions directly affects the high and low level switching generated when the instruction is switched, which directly affects the power consumption of the processor. At the same time, the difference in encoding between instructions also directly affects the logic complexity of the processor’s decoding process, directly affects the length of the critical path, and thus affects the operating frequency of the processor. So in the process of RISC processor design, the problem of coding of instruction set is very important. In the design of this processor, we classify all instructions from the number of operands and instruction relevance. Table1 is the processor arithmetic instructions, Table 2 is the control instruction, Table 3 is the jump instruction, Table 4 is the interrupt related instruction, and Table 5 is the memory access instruction.Table 1

For functional verification, the function implementation of the FIR filter in this article is written in C language. Since the processor does not have the decimal type, this article performs fixed-point processing on the data. The fixed-point structure is fix (1, 16, 15), that is, 1 sign bit, 0 integer bit, and 15 decimal places. The experimental results are shown in Figure7.Figure 7
Filtering experiment results.

The amplitude-frequency characteristics of the input model(b)
The amplitude-frequency response curve of the FIR filterFrom the performance analysis point of view, the same FIR filter is compared with the performance of the executable code compiled by the C compiler on the processors with and without MAC instructions. The C language code is compiled into assembly code by the compiler, the number of generated assembly code instructions is 253, contains two levels of nested loops, and the loop degree is low. For processors without MAC instructions, the number of assembly code instructions compiled by the compiler is 257 and contains a large number of loop nests. It can be seen that the introduction of MAC instructions does not greatly increase the instruction density of the generated code, but due to the different degrees of looping in the code, the introduction of MAC instructions greatly reduces the number of execution clocks of the processor. Therefore, the introduction of the MAC instruction greatly improves the processing speed of the multiply-accumulate operation of the processor and improves the execution efficiency of the processor.


### 3.2. End-to-End Delay Test Experiment

In order to test the effect of the end-to-end experiment in the network calculus theory, this paper calculates the change of the delay bound with the number of data streams and the end-to-end delay result obtained by the point-by-point addition according to the method in the statistical network calculation; the experimental results are shown in Figure8.Figure 8

As the number of data streams increases, the delay boundary has not changed much at the beginning. However, when it increases to a certain value, the delay bound increases sharply, indicating that the network condition has deteriorated and data can no longer be transmitted normally. At the same time, this paper also compares the situation of different node numbers. It can be seen that the results obtained by statistical network calculation are still very compact as the number of nodes increases.

## 5. Conclusions

This article mainly studies the intelligent art design management based on wireless communication microprocessor and mobile Internet. Therefore, this paper proposes the combination of inspection technology and T2 microprocessor with von Neumann structure and Harvard structure and instruction set to design a microprocessor based on wireless communication. Then, by combining the SOA service architecture of the mobile Internet and integrating the theory of art design management, an intelligent art design management model based on wireless communication microprocessors and mobile Internet is constructed. Then, in order to optimize this new type of artistic design management mode, this paper designs a finite impulse response (FIR) filter test experiment and an end-to-end delay test experiment to collect data. Then the data is optimized for the intelligent art design management mode based on wireless communication microprocessor and mobile Internet. Finally, in order to verify its ability in practical application, this paper also designed a controlled experiment and a questionnaire survey experiment. Experiments have proved that the art design management mode based on wireless communication microprocessors and mobile Internet can greatly improve the artistic creation ability and can also slightly improve the management ability, and this mode is relatively easy to accept and can be liked by most people.
