MIPS 01

Last modified: Feb 15, 2026

I think I will be talking about some random MIPS stuff.

Basic Formatting

.data
    example_variable: .word 0

.text
.globl main

main:
    #end program
    li $v0, 10
    syscall 

Testing / Compiling

JsSpim This is a very good online MIPS emulator. I found it more useful and user-friendly than the Homebrew spim that I was originally using.

Syscall

While I was working on the homework, I found this website: syscall reference. It is very well documented. The basic use of syscall is shown above as well. If you want to take integer input, this is what you need to do.

main:
    # int t0 = getchar()
    li $v0, 5
    syscall 
    move $t0, $v0

Stack Pointer

These two videos gave me enough of an explanation.
