Q: Information: - A peripheral is "an ancillary device used to put information into and get information out of the computer". - A microprocessor is a computer processor which incorporates the functions of a computer's central processing unit (CPU) on a single integrated circuit (IC), or at most a few integrated circuits. The microprocessor is a multipurpose, clock driven, register based, programmable electronic device which accepts digital or binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic. Microprocessors operate on numbers and symbols represented in the binary numeral system. - In digital circuit theory, combinational logic (sometimes also referred to as time-independent logic ) is a type of digital logic which is implemented by Boolean circuits, where the output is a pure function of the present input only. This is in contrast to sequential logic, in which the output depends not only on the present input but also on the history of the input. In other words, sequential logic has "memory" while combinational logic does not. - The R3000 is a full 32 bit RISC microprocessor chipset developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture ( ISA ) . Introduced in June 1988 , it was the second MIPS implementation , succeeding the R2000 as the flagship MIPS microprocessor . It operated at 20 , 25 and 33.33 MHz. The MIPS 1 instruction set is very small compared to the instruction sets of other microprocessors , such as the contemporary 80x86 , 680x0 architectures ) , as it includes only most commonly used instructions and supports very limited number of addressing modes . The small number of CPU instructions , as well as other instruction set features -- fixed instruction length and only three different types of instruction formats -- greatly simplify instruction decoding and processing . To speed up processing even further the CPU employs a 5 - stage instruction pipeline . The pipeline design allows the R3000 CPU to execute most instructions at a rate close to 1 instruction per cycle . In addition to the CPU core , the R3000 microprocessor includes a Control Processor ( CP ) , which contains a Translation Lookaside Buffer and a Memory Management Unit . The CP works as a coprocessor . Besides the CP , the R3000 can also support an external R3010 numeric coprocessor and two other external coprocessors . The R3000 CPU does not include its own level 1 cache . Instead , the processor has an on - chip cache controller which controls separate external data and instruction caches . The size of each external cache can be as large as 256 KB . The CPU can access both caches during the same CPU cycle . The R3000 found much success and was used by many companies in their workstations and servers . Users included : Ardent Computer Digital Equipment Corporation ( DEC ) for their DECstation workstations and multiprocessor DECsystem servers Evans & Sutherland for their Vision ( ESV ) series workstations MIPS Computer Systems for their MIPS RISC / os Unix workstations and servers . NEC for their RISC EWS4800... - A motherboard (sometimes alternatively known as the mainboard, system board, baseboard, planar board or logic board, or colloquially, a mobo) is the main printed circuit board (PCB) found in general purpose microcomputers and other expandable systems. It holds and allows communication between many of the crucial electronic components of a system, such as the central processing unit (CPU) and memory, and provides connectors for other peripherals. Unlike a backplane, a motherboard usually contains significant sub-systems such as the central processor, the chipset's input/output and memory controllers, interface connectors, and other components integrated for general purpose use. - In a computer system, a chipset is a set of electronic components in an integrated circuit that manages the data flow between the processor, memory and peripherals. It is usually found on the motherboard. Chipsets are usually designed to work with a specific family of microprocessors. Because it controls communications between the processor and external devices, the chipset plays a crucial role in determining system performance. - A computer is a device that can be instructed to carry out an arbitrary set of arithmetic or logical operations automatically. The ability of computers to follow a sequence of operations, called a "program", make computers very flexible and useful. Such computers are used as control systems for a very wide variety of industrial and consumer devices. This includes simple special purpose devices like microwave ovens and remote controls, factory devices such as industrial robots and computer assisted design, but also in general purpose devices like personal computers and mobile devices such as smartphones. The Internet is run on computers and it connects millions of other computers. - An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, normally silicon. The integration of large numbers of tiny transistors into a small chip resulted in circuits that are orders of magnitude smaller, cheaper, and faster than those constructed of discrete electronic components. The IC's mass production capability, reliability and building-block approach to circuit design ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones, and other digital home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs. Given the paragraphs above, decide what entity has the relation 'subclass of' with 'central processing unit'.
