For the rest of this subject, we will be using a RISC architecture, the MIPS ISA, as our representative architecture both for studying instruction sets and for examining how a CPU actually works. MIPS was the pioneer chip-based RISC architecture, originally designed in 1981 at Stanford University, and one of the first CPUs to be heavily pipelined to improve performance. Instruction Set Architectures (ISAs) •ISA defines the interface which hardware presents to software •A compiler translates high-level source code (e.g., C++, Go) to the ISA for a target processor •The processor directly executes ISA instructions •Example ISAs: •MIPS (mostly the focus of CS 161) •ARM (popular on mobile devices) MIPS Green Sheet - MIPS Instruction Set Architecture.

MIPS® Architecture For Programmers Volume I-A: Introduction to the MIPS32® Architecture, Revision 6.01 6 Architecture • Volume II provides detailed descriptions of each instruction in the MIPS32™ instruction set • Volume III describes the MIPS32™ Privileged Resource Architecture which de?nes and governs the behavior of the privileged resources included in a MIPS32™ processor implementation Firstly, instruction set is merely a synonym (arguably a poor one) for architecture, which is itself a contraction of computer architecture. MIPS is a computer architecture. Two classic books on MIPS, Gerry Kane and Joe Heinrich's MIPS RISC Architecture and Dominic Sweetman's See MIPS Run supports this. An instruction set architecture (ISA) is an abstract model of a computer.It is also referred to as architecture or 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. MIPS used 32 registers, each 32 bits wide (a bit pattern of this size is referred to as a word). Instruction Set The MIPS instruction set consists of about 111 total instructions, each represented in 32 bits. An example of a MIPS instruction is below: The MIPS Open initiative will be moderated by Wave Computing and an Advisory Committee that will include industry-leading OEMs, partners, universities and technology luminaries Wave Computing, on Monday, announced that it will open source its MIPS instruction set architecture (ISA) to accelerate the MIPS Arithmetic and Logic Instructions COE 301 Computer Organization Prof. Muhamed Mudawar College of Computer Sciences and Engineering King Fahd University of Petroleum and Minerals MIPS gives you a right and license under our R6 architecture patents to design, build and sell cores and use of the "MIPS Certified" trademark logo for certified cores.
