Register Addressing Mode
- Instruction Operand is in a Register (

Immediate Addressing Mode
- Instruction Operand is in a Instruction directly (
addi $t1, $t2, 98)
Displacement Addressing Mode
- Instruction Operand is in memory with Memory Address calculated as
Base + Offset(lw $t1, 20($t2))
PC-relative Addressing Mode
- Instruction Operand is the sum of Program Counter and constant in the instruction (
beq,bne)
