We know that both program instructions and data operands are stored in the memory. To execute an instruction processor has to fetch instruction and read the operand or operands if necessary from the memory.

In MIPS assembly language, registers $50 to $s7 map onto registers 16 to 23, and registers $t0 to $t7 map onto registers 8 to 15. The opcode in MIPS instruction set architecture is only 6 bits. This means there are only 64 possible instructions. `
