WebMIPS Encoding: Basics 5 Each MIPS instruction has a fixed-length of 32 bits ° All relevant information for an operation must be encoded with these bits! Additional challenge: To reduce the complexity of processor design, the instruction encodings should be as regular as possible ° Small number of formats, i.e. as few variations as possible WebThe 6-bit opcode is split into two 3-bit opcodes. The row is the first three bits and the column is the second three. Our opcode is 000_000, so the first three bits 000 show us …
