Question

I have a working program that multiplies integers to give a result in MIPS. My only problem is that I need the result to be printed in hex not decimal format. Below is my program, followed by another program that converts from decimal to hex but I need a way to implement the second (conversion) program into the first. Thanks!

First program (the multiplication program):
.data
out_string: .asciiz "The result is: "

.text
main: li $v0, 5
syscall
move $t0, $v0
li $v0, 5
syscall
move $t1, $v0
li $v0, 5
syscall
move $t2, $v0
li $v0, 5
syscall
mult $t2, $v0
mfhi $t3
mflo $t2
mult $t0, $t1
mfhi $t1
mflo $t0
mult $t3, $t1 #hi
mflo $t1
mult $t2, $t0 #lo
mflo $t0
mfhi $t2

li $v0, 4
la $a0, out_string
syscall

li $v0, 1
move $a0, $t1
syscall

li $v0, 1
move $a0, $t2
syscall

li $v0, 1
move $a0, $t0
syscall

li $v0, 10
syscall

-----------------------------------------------------------------------
Second program (converts from decimal to hex, needs to be implemented into first program):
.data

prompt: .asciiz "Enter the decimal number to convert: "
ans: .asciiz " Hexadecimal equivalent: "
result: .space 8

.text
.globl main

main:

la $a0, prompt
li $v0, 4
syscall

li $v0, 5
syscall

move $t2, $v0

la $a0, ans
li $v0, 4
syscall

li $t0, 8 # counter
la $t3, result # where answer will be stored

Loop:

beqz $t0, Exit # branch to exit if counter is equal to zero
rol $t2, $t2, 4 # rotate 4 bits to the left
and $t4, $t2, 0xf # mask with 1111
ble $t4, 9, Sum # if less than or equal to nine, branch to sum
addi $t4, $t4, 55 # if greater than nine, add 55

b End

Sum:

addi $t4, $t4, 48 # add 48 to result

End:

sb $t4, 0($t3) # store hex digit into result
addi $t3, $t3, 1 # increment address counter
addi $t0, $t0, -1 # decrement loop counter

j Loop

Exit:

la $a0, result
li $v0, 4
syscall

la $v0, 10
syscall

Explanation / Answer

Dear..    # Write a MIPS code that asks the user for decimal number
# Convert it to hex and print the result

            .data prompt: .asciiz "Enter the decimal number to convert: " ans: .asciiz " Hexadecimal equivalent: " result: .space 8             .text             .globl main main:             la $a0, prompt             li $v0, 4             syscall             li $v0, 5             syscall             move $t2, $v0             la $a0, ans             li $v0, 4             syscall             li $t0, 8                                # counter             la $t3, result                         # where answer will be stored Loop:             beqz $t0, Exit                       # branch to exit if counter is equal to zero             rol $t2, $t2, 4                       # rotate 4 bits to the left             and $t4, $t2, 0xf                   # mask with 1111             ble $t4, 9, Sum                     # if less than or equal to nine, branch to sum             addi $t4, $t4, 55                   # if greater than nine, add 55             b End             Sum:                         addi $t4, $t4, 48          # add 48 to result End:             sb $t4, 0($t3)                          # store hex digit into result             addi $t3, $t3, 1                        # increment address counter             addi $t0, $t0, -1                       # decrement loop counter j Loop Exit:             la $a0, result             li $v0, 4             syscall             li $v0, 10             syscall Exit:             la $a0, result             li $v0, 4             syscall             li $v0, 10             syscall what you give the code is correct. Just need to change the code instead of la $v0, 10, you should have li $v0, 10.

i give u the samplecode for multiplication of two integers. mult proc; multiplies eax by ebx and places result in edx:ecx
    xor ecx, ecx
    xor edx, edx mul1:
    test ebx, 1     jz mul2     add ecx, eax     adc edx, 0 mul2:     shr ebx, 1     shl eax, 1     test ebx, ebx     jnz mul1 done:     ret mult endp
