Hi all,
What is the best method to convert from decimal to hexadecimal in MIPS? I'm currently working with using rol, andi, ori and an array size of 16 with two counter variables one to increment and one to decrement.
Thanks
Jo

Here is my code so far:
Because I am still learning this language, easiest to understand would work better for me.
array: .word 0:50
.data
strintro: .asciiz "\nThis program will read an interger
from the keyboard and convert it to its hexadecimal value.
Upon exit the program will print the corresponding string
of hexadecimal characters.\n"
strin: .asciiz "\nPlease enter a positive interger: "
strhex: .asciiz "\nThe string of hex characters: "
strnl: .asciiz "\n"
.text
main: addi $t1, $0, 9
addi $t3, $0, 1
la $s0, array
li $v0, 4
la $a0, strintro
syscall
read: li $v0, 4
la $a0, strin
syscall
li $v0, 5
syscall
slt $t2, $v0, $t1
beq $t2, $t3, equal
bne $t2, $t3, check
equal: sw $v0, 0($s0)
addi $s0, $s0, 4
j read
check: slti $t4, $v0, 15
bne $t4, $0, convert
convert: #I know I need to compare the 4 LSB's from each number but should I convert to binary first and when I compare
#do I need a series of if tests to print the hex character.
