3.3 Memory Addressing Modes
Memory addresses are byte addresses, so memory addressing is performed with three types of load
instructions and two types of store instructions. Swap instructions have the same memory
addressing as store instructions.
3.3.1 Load Instruction Addressing
1. Base + Index
The effective address (EA) is obtained by adding the values of any two general registers %r0-31
specified.
2. Base + Displacement
The effective address (EA) is obtained by adding the value of any general register %r0-31 specified
and a displacement given by the instruction’s immediate value field.
3.3.2 Store Instruction Addressing
1. Base + Displacement
The effective address (EA) is obtained by adding the value of any general register %r0-31 specified
and a displacement given by the instruction’s immediate value field.
EA = [reg_S1 + reg_S2]
EA = [reg_S1] + offS
EA = [reg_S1] + offS
