Question

1. Two integer numbers a=10 and b=20 are stored in the data segment of the memory. The number a is stored in Mem[0x10010000] and b is stored in Mem[0x10010004]. Write MIPS assembly code to swap the two numbers, load a to a register, b to another register and store a at Mem[0x10010004], store b at Mem[0x10010000].

Answer 1

code:

.text
li $a,0x10010000 //loading a value into memory location
li $b,0x10010004 //loading b value into memory location

move $t,$a //moving a value to new register

move $a,,$b       //swapping a and b value

move $b,$t //swapping a to b
