Machine Instructions

Question

What is the difference between LOAD/STORE & MOVE instructions?Are they CPU - architecture dependent?

Answer 1

LOAD is used to load data from memory to accumulator.

STORE is used to store the accumulator result in memory.

Both LOAD and STORE are 1-address instructions.

MOVE is used to move contents of a register to memory and vice versa or from one register to another

MOV is a 2-address instruction.

@ just_bhavana LOAD/STORE can be 2-address instruction
Load r8,0(r4)
content of memory location addressed by r4 is loaded into the register r8.
