Instruction Set

Note: I think the thingy that colors the code doesn’t really understand MIPS, so the coloring might be a little weird. I appologize for the inconvience.

Reading & Writing

lw -> load word
lh -> load half-word
lb -> load byte

lw $s0, len # read from len and write to $s0

li -> load immediate

li $s0, 5 # set $s0 to 5

la -> load address

la $s0, arr # get the address of array and give it to $s0

move -> moves values between registers

move $t0, $s0 # read from $s0 and write to $t0

sw -> store word
sh -> store half-word
sb -> store byte

sw $s0, max # read from $s0 and write to max

Math

ALl basic operations work the same, but with a different first word
add, sub, mul, div, rem, abs

add $s0, $t0, 5 # $s0 = $t0 + 5

Note: rem is its own command
subu, addu, etc are unsigned

Jumping (called branching)

bge $t0, $t5, label

Note: all branch commands are 3 letters, so it is bgt instead of just bg
