Question

MIPS Assembly:

For these programming exercises, use only those instructions that have been discussed so far in these notes:

Put the bit pattern 0x55555555 in register $1. (Do this with three instructions.)

Now shift the pattern left one position into register $2 (leave $1 unchanged).

Put the the bit-wise OR of $1 and $2 into register $3. Put the the bit-wise AND of $1 and $2 into register $4. Put the the bit-wise XOR of $1 and $2 into register $5.

Examine the results.

Explanation / Answer

.data
msg0: .asciiz "value after performing shift operation"
msg1: .asciiz "value after performing OR operation"
msg2: .asciiz "value after performing AND operation"
msg3: .asciiz "value after performing XOR operation"

.text
.globl main

main:
li $t1,0x55555555   #loading 0x55555555 into register $t0

sll $t2,$t2,$t1       #left shift operation on $t2
or $t3,$t2,$t1       #or operation on $t1 and $t2
