Question: who introduced the first microprocessor for the developer of Clarkdale in 1971?

full_context: Document 1: Wolfdale (microprocessor): Wolfdale is the code name for a processor from Intel that is sold in varying configurations as Core 2 Duo, Celeron, Pentium and Xeon. In Intel's Tick-Tock cycle, the 2007/2008 "Tick" was Penryn microarchitecture, the shrink of the Core microarchitecture to 45 nanometers as CPUID model 23. This replaced the Conroe processor with "Wolfdale".
Document 2: Home computer: The invention of the Intel 8080 microprocessor chip in April 1974 made practical the development of the (relatively) affordable mass - market microcomputer. In the USA this first appeared in early 1975 in the form of an unassembled kit, the Altair 8800; shortly afterward pre-assembled Altairs were offered. The sudden popularity of desktop computers happened because the 8080 CPU could represent and manipulate 256 discrete values in its 8 - bit registers. Thus the 7 - bit ASCII standard for the representation of alphanumeric data became feasible for the first time in a machine much smaller and less expensive than the furniture - size minicomputers, with their processors that occupied entire circuit boards. This new class of computer was practical for serious work because it could input, process, and output alphanumeric information. It also enabled sophisticated programs such as database managers and BASIC interpreters to become available to a larger market consisting of people possessing lesser technical skills.
Document 3: Personal computer: 1974 saw the introduction of what is considered by many to be the first true ``personal computer '', the Altair 8800 created by Micro Instrumentation and Telemetry Systems (MITS). Based on the 8 - bit Intel 8080 Microprocessor, the Altair is widely recognized as the spark that ignited the microcomputer revolution as the first commercially successful personal computer. The computer bus designed for the Altair was to become a de facto standard in the form of the S - 100 bus, and the first programming language for the machine was Microsoft's founding product, Altair BASIC.
Document 4: Conroe (microprocessor): Conroe is the code name for many Intel processors sold as Core 2 Duo, Xeon, Pentium Dual-Core and Celeron. It was the first desktop processor to be based on the Core microarchitecture, replacing the NetBurst microarchitecture based Cedar Mill processor. It has product code 80557, which is shared with "Allendale" and "Conroe-L" that are very similar but have a smaller L2 cache. Conroe-L has only one processor core and a new CPUID model. The mobile version of Conroe is Merom, the dual-socket server version is Woodcrest, and the quad-core desktop version is Kentsfield.
Document 5: Clarkdale (microprocessor): Clarkdale is the code name for an Intel processor, initially sold as desktop Intel Core i5 and Core i3 and Pentium. It is closely related to the
Document 6: CMOS: Complementary metal–oxide–semiconductor (CMOS) is a technology for constructing integrated circuits. CMOS technology is used in microprocessors, microcontrollers, static RAM, and other digital logic circuits. CMOS technology is also used for several analog circuits such as image sensors (CMOS sensor), data converters, and highly integrated transceivers for many types of communication. Frank Wanlass invented CMOS in 1963 while at Fairchild Semiconductor and was granted US patent 3,356,858 in 1967. In this groundbreaking patent, the fabrication of CMOS devices was outlined, on the basis of thermal oxidation of a silicon substrate to yield a layer of silicon dioxide located between the drain contact and the source contact .
Document 7: Bloomfield (microprocessor): Bloomfield is the code name for Intel high-end desktop processors sold as Core i7-9xx and single-processor servers sold as Xeon 35xx., in almost identical configurations, replacing the earlier Yorkfield processors. The Bloomfield core is closely related to the dual-processor Gainestown, which has the same CPUID value of 0106Ax (family 6, model 26) and which uses the same socket. Bloomfield uses a different socket than the later Lynnfield and Clarksfield processors based on the same 45 nm Nehalem microarchitecture, even though some of these share the same Intel Core i7 brand.
Document 8: Intel 4004: The chip design started in April 1970, when Federico Faggin joined Intel, and it was completed under his leadership in January 1971. The first commercial sale of the fully operational 4004 occurred in March 1971 to Busicom Corp. of Japan for which it was originally designed and built as a custom chip. In mid-November of the same year, with the prophetic ad ``Announcing a new era in integrated electronics '', the 4004 was made commercially available to the general market. The 4004 was the first commercially available monolithic CPU, fully integrated in one small chip. Such a feat of integration was made possible by the use of the then - new silicon gate technology for integrated circuits, originally developed by Faggin (with Tom Klein) at Fairchild Semiconductor in 1968, which allowed twice the number of random - logic transistors and an increase in speed by a factor of five compared to the incumbent MOS aluminum gate technology. Faggin also invented the bootstrap load with silicon gate and the`` buried contact'', improving speed and circuit density compared with aluminum gate.
Document 9: Computer: This new development heralded an explosion in the commercial and personal use of computers and led to the invention of the microprocessor. While the subject of exactly which device was the first microprocessor is contentious, partly due to lack of agreement on the exact definition of the term "microprocessor", it is largely undisputed that the first single-chip microprocessor was the Intel 4004, designed and realized by Ted Hoff, Federico Faggin, and Stanley Mazor at Intel.
Document 10: Skylake (microarchitecture): Skylake is the codename used by Intel for a processor microarchitecture that was launched in August 2015 succeeding the Broadwell microarchitecture. Skylake is a microarchitecture redesign using the same 14 nm manufacturing process technology as its predecessor, serving as a "tock" in Intel's "tick–tock" manufacturing and design model. According to Intel, the redesign brings greater CPU and GPU performance and reduced power consumption. Skylake CPUs share its microarchitecture with Kaby Lake, Coffee Lake and Cannon Lake CPUs.
Document 11: Computer: The first practical ICs were invented by Jack Kilby at Texas Instruments and Robert Noyce at Fairchild Semiconductor. Kilby recorded his initial ideas concerning the integrated circuit in July 1958, successfully demonstrating the first working integrated example on 12 September 1958. In his patent application of 6 February 1959, Kilby described his new device as "a body of semiconductor material ... wherein all the components of the electronic circuit are completely integrated". Noyce also came up with his own idea of an integrated circuit half a year later than Kilby. His chip solved many practical problems that Kilby's had not. Produced at Fairchild Semiconductor, it was made of silicon, whereas Kilby's chip was made of germanium.
Document 12: Pentium III: The Pentium III (marketed as Intel Pentium III Processor, informally PIII) brand refers to Intel's 32 - bit x86 desktop and mobile microprocessors based on the sixth - generation P6 microarchitecture introduced on February 26, 1999. The brand's initial processors were very similar to the earlier Pentium II - branded microprocessors. The most notable differences were the addition of the SSE instruction set (to accelerate floating point and parallel calculations), and the introduction of a controversial serial number embedded in the chip during the manufacturing process.
Document 13: Merom (microprocessor): "Merom" is the code name for various Intel processors that are sold as Core 2 Duo, Core 2 Solo, Pentium Dual-Core and Celeron. It was the first mobile processor to be based on the Core microarchitecture, replacing the Enhanced Pentium M based Yonah processor. Merom has the product code 80537, which is shared with "Merom-2M" and "Merom-L" that are very similar but have a smaller L2 cache. Merom-L has only one processor core and a different CPUID model. The desktop version of Merom is Conroe and the dual-socket server version is Woodcrest. Merom was manufactured in a 65 nanometer process, and was succeeded by Penryn, a 45 nm version of the Merom architecture. Together, Penryn and Merom represented the first 'tick-tock' in Intel's Tick-Tock manufacturing paradigm, in which Penryn was the 'tick' (new process) to Merom's 'tock' (new architecture).
Document 14: Computer: The next great advance in computing power came with the advent of the integrated circuit. The idea of the integrated circuit was first conceived by a radar scientist working for the Royal Radar Establishment of the Ministry of Defence, Geoffrey W.A. Dummer. Dummer presented the first public description of an integrated circuit at the Symposium on Progress in Quality Electronic Components in Washington, D.C. on 7 May 1952.
Document 15: Microprocessor: By the late 1960s, designers were striving to integrate the central processing unit (CPU) functions of a computer onto a handful of MOS LSI chips, called microprocessor unit (MPU) chipsets. Building on an earlier Busicom design from 1969, Intel introduced the first commercial microprocessor, the 4 - bit Intel 4004, in 1971, followed by its 8 - bit microprocessor 8008 in 1972. In 1969, Lee Boysel, b 8 - bit arithmetic logic units (3800 / 3804) he designed earlier at Fairchild, created the Four - Phase Systems Inc. AL - 1, an 8 - bit CPU slice that was expandable to 32 - bits. In 1970, Steve Geller and Ray Holt of Garrett AiResearch designed the MP944 chipset to implement the F - 14A Central Air Data Computer on six metal-gate chips fabricated by AMI.
