I need to do a program in MIPS. It needs to convert a hexadecimal to binary and convert a decimal to hexadecimal. I figured out how to do the decimal to hexadecimal below, but I have no idea on how to do hexadecimal to binary. Could someone help me with the hexadecimal to binary?

This is my Decimal to hexadecimal:

.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
