Assembly

RISC-V (pronounced “risk-five”) is an open, royalty-free RISC ISA originally designed to support academic research and education, and now increasingly used in commercial silicon. Unlike MIPS, ARM, or x86, RISC-V is not owned by any single company — its specification is maintained by RISC-V International, and anyone is free to implement it without paying licensing fees. This openness, combined with a deliberately small and modular base ISA, has made it popular in everything from microcontrollers to research CPUs to (increasingly) high-performance application processors. ...

MIPS (Microprocessor without Interlocked Pipeline Stages) assembly is one of the RISC ISA’s. It was developed in the early 1980s at Stanford University by Professor John L. Hennessy. MIPS is widely used in academic research and industry, particularly in computer architecture courses due to its straightforward design and in various embedded systems applications for its efficiency and performance. History The first MIPS processor, the R2000, was introduced. It implemented the MIPS I architecture, which was one of the earliest commercial RISC processors. There are multiple versions of MIPS: including MIPS I, II, III, IV, and V; as well as five releases of MIPS32/64. MIPS I had 32-bit architecture with basic instruction set and addressing modes. MIPS III introduced 64-bit architecture in 1991, increasing the address space and register width. ...
