Questions tagged [mips]
MIPS is a RISC instruction set architecture (ISA). It is commonly used in embedded devices such as set top boxes and networking gear. Many university-level computer architecture classes use the MIPS ISA due to its relative simplicity. If your question is about MIPS assembly and machine code, also add the assembly tag.
