MIPS

Definition

MIPS, which stands for Microprocessor without Interlocked Pipeline Stages, is a computer architecture that uses a RISC (Reduced Instruction Set Computer) design. It is known for its simplicity and efficiency, featuring a small set of instructions that are executed in a single cycle. This allows for faster performance and easier implementation in various computing environments, making MIPS a popular choice in both academic settings and embedded systems.
