Question

Translate the code in translateMe.c to MIPS in a file called translated.asm.Make sure you run both versions of the programto see that they get the same result.

Code:

int main() {
// use $t0 for x
int x = 0xC0FFEE00;
  
// use $t1 for y
unsigned int y = 0xC0FFEE00;

// use $t2 for z
int z = (x >> 8) & 0xFF;

// use $t3 for w
int w = ((y | 0xFF000000) << 6) ^ 0xFF;
}

Greetings!!

Code in C:

#include <stdio.h>
#include <stdlib.h>

int main()
{
// use $t0 for x
int x = 0xC0FFEE00;
printf("%x\n",x);

// use $t1 for y
unsigned int y = 0xC0FFEE00;
printf("%x\n",y);

// use $t2 for z
int z = (x >> 8) & 0xFF;
printf("%x\n",z);

// use $t3 for w
int w = ((y | 0xFF000000) << 6) ^ 0xFF;
printf("%x\n",w);

return 0;
}

Code in MIPS

.data
nl: .asciiz "\n"
.text
li $t0,0xC0FFEE00   #load 0xC0FFEE00 into t0
li $t1,0xC0FFEE00   #load 0xC0FFEE00 into t1
#int z = (x >> 8) & 0xFF;
srl $t2,$t0,8       #shift x right by 8 and store result in t2
andi $t2,$t2,0xFF   #AND content of t2 with FF and store the result in t2
#int w = ((y | 0xFF000000) << 6) ^ 0xFF;
ori $t3,$t1,0xFF000000   #OR x with FF000000 and store the result in t3
sll $t3,$t3,6       #shift t3 content right by 6
xori $t3,$t3,0xFF   #XOR t3 with FF
#print x
move $a0,$t0
li $v0,34
syscall
#print newline
la $a0,nl
li $v0,4
syscall
#print y
move $a0,$t1
li $v0,34
syscall
#print newline
la $a0,nl
li $v0,4

#print z
move $a0,$t2
li $v0,34
syscall
#print newline

#print w

Hope this helps

Thank You
