MIPSarkkitehtuuria

MIPSarkkitehtuuria refers to the MIPS (Microprocessor without Interlocked Pipeline Stages) instruction set architecture. MIPS is a Reduced Instruction Set Computer (RISC) architecture known for its simplicity and efficient pipelining. It was originally developed by John Hennessy and his team at Stanford University in the early 1980s.

The core design principle of MIPS is to use a relatively small number of simple instructions that execute in a fixed number of clock cycles. This simplicity allows for a highly efficient pipeline, where multiple instructions can be in different stages of execution simultaneously. This pipelining significantly boosts performance compared to older Complex Instruction Set Computer (CISC) architectures.

MIPS architectures are characterized by their load/store design, meaning that only load and store instructions can access memory. All other operations, such as arithmetic and logic operations, are performed on data held in registers. This separation simplifies instruction decoding and execution.

Over the years, various versions of the MIPS architecture have been developed, including MIPS I, MIPS II, MIPS III, MIPS IV, MIPS V, and the MIPS32 and MIPS64 families. These revisions introduced enhancements such as floating-point support, larger address spaces, and improved instruction sets. MIPS processors have been widely used in embedded systems, routers, game consoles like the Nintendo 64 and PlayStation, and in some workstations. While its prominence in personal computers has waned, MIPS remains a relevant architecture in specific embedded applications due to its performance and power efficiency.
