Instruction length - assembly language, Computer Engineering

Instruction Length:

Variable-length instructions (Intel 80x86, VAX) need multi-step fetch and decode, but permit for a much more flexible and compressed instruction set.
Fixed-length instructions permit easy fetch and decode, and simplify parallelism and pipelining.

All of the MIPS instructions are 32 bits long.

-this decision put effect on every other ISA decision we make because it build instruction bits scarce.

MIPS instruction format

The opcode tells the machine which format
So add r1,r2,r3 has

- Opcode=0, funct=32,rs=2,rt=3,rd=1,sa=0

- 000000 00010 00011 00001 0000 100000
