Question

WPte a program that asks the user for 2 numbers. the program should then add the 2 numbers bit by bit, using boolean operators no arithmetic operations ex: add, addi, sub, mult, div or arrays are permitted in this project. forming a new variable (in a register) with the solution. That solution is to be output bit by bit using the function that was written in class do not use syscall with a value 10 in vo (no print character, no print binary) memory (oading and storing) is not permitted in this program. extra credit in addition to outputting all the values in binary, output the 3 numbers in hex mitted to use addi as a loop contral only for the extra credit portion of the program you are per You are also permitted to store the hex values in memory, and do a table lookup from memory (extra credit anly)

using mips for assembly language

Answer 1

add(int, int):

addiu $sp,$sp,-24

sw $fp,20($sp)

move $fp,$sp

sw $4,24($fp)

sw $5,28($fp)

$L3:

lw $3,24($fp)

lw $2,28($fp)

nop

and $2,$3,$2

sw $2,8($fp)

lw $3,24($fp)

lw $2,28($fp)

nop

xor $2,$3,$2

sw $2,12($fp)

lw $2,8($fp)

nop

sll $2,$2,1

sw $2,24($fp)

lw $2,12($fp)

nop

sw $2,28($fp)

lw $2,8($fp)

nop

beq $2,$0,$L2

nop

b $L3

nop

$L2:

lw $2,12($fp)

move $sp,$fp

lw $fp,20($sp)

addiu $sp,$sp,24

j $31

nop

$LC0:

.ascii "Enter two numbers\000"

$LC1:

.ascii "%d%d\000"

$LC2:

.ascii "Addition = &d\000"

main:

addiu $sp,$sp,-48

sw $31,44($sp)

sw $fp,40($sp)

move $fp,$sp

lui $2,%hi($LC0)

addiu $4,$2,%lo($LC0)

jal printf

nop

addiu $3,$fp,32

addiu $2,$fp,28

move $6,$3

move $5,$2

lui $2,%hi($LC1)

addiu $4,$2,%lo($LC1)

jal scanf

nop

lw $2,28($fp)

lw $3,32($fp)

nop

move $5,$3

move $4,$2

jal add(int, int)

nop

sw $2,24($fp)

lw $5,24($fp)

lui $2,%hi($LC2)

addiu $4,$2,%lo($LC2)

jal printf

nop

move $2,$0

move $sp,$fp

lw $31,44($sp)

lw $fp,40($sp)

addiu $sp,$sp,48

j $31

nop

Hope this helps.

Thank you.
