MIPS (Microprocessor without Interlocked Pipelined Stages) [1] is a family of reduced instruction set computer (RISC) instruction set architectures (ISA) [2]: A-1 [3]: 19 developed by MIPS Computer Systems, now MIPS Technologies, based in the United States.
The SGI commercial designs deviated from Stanford MIPS by implementing most of the interlocks in hardware, supplying full multiply and divide instructions (among others). The designs were guided, in part, by software architect Earl Killian who designed the MIPS III 64-bit instruction-set extension, and led the work on the R4000 microarchitecture.
This is a list of processors that implement the MIPS instruction set architecture, sorted by year, process size, frequency, die area, and so on. These processors are designed by Imagination Technologies, MIPS Technologies, and others. It displays an overview of the MIPS processors with performance and functionality versus capabilities for the ...
An instruction set architecture (ISA) is an abstract model of a computer, also referred to as computer architecture.A realization of an ISA is called an implementation.An ISA permits multiple implementations that may vary in performance, physical size, and monetary cost (among other things); because the ISA serves as the interface between software and hardware.
The MIPS32 architecture is a high-performance 32-bit instruction set architecture (ISA) that is used in applications such as 32-bit microcontrollers, home entertainment, home networking devices and mobile designs. [76]
The R2000 is a 32-bit microprocessor chip set developed by MIPS Computer Systems that implemented the MIPS I instruction set architecture (ISA). Introduced in January 1986, it was, by a few months, the first commercial implementation of a RISC architecture.
This figure demonstrates how one type of MIPS32 instruction word is decoded. The first six bits specify the operation (add immediate). The second and third groups of five bits each specify the number of one of MIPS32's 32 general-purpose registers (GPR). The first group specifies the destination GPR, and the second specifies the source GPR.
The R4000 is a microprocessor developed by MIPS Computer Systems that implements the MIPS III instruction set architecture (ISA). Officially announced on 1 October 1991, it was one of the first 64-bit microprocessors and the first MIPS III implementation.
