System call mips
WebThe term MIPS is an acronym for Microprocessor without Interlocked Pipeline Stages. It is a reduced-instruction set architecture developed by an organization called MIPS Technologies. The MIPS assembly language is a very useful language to learn because many embedded systems run on the MIPS processor.
