MIPS ASSEMBLY LANGUAGE

3 types:

1) Memory-reference instructions

2) Arithmetic-logical instructions

3) Branch and Jump instructions

Simple operations in MIPS:

C version:

f = (g + h) [where f, g, and h are assigned to registers $s0, $s1, $s2]

MIPS version:

add $s0, $s1, $s2

C Version:

f = (i + j) [where f, i, and h are assigned to registers $s0, $s3, $s4]

MIPS Version:

sub $s0, $s3, $s4

C Version:

g = h + A[8] [where g and h assigned to registers $s1, $s2, t registers are temporary registers]

MIPS Version:

lw $t0, 8($s3)

add $s1, $s2, $t0

C Version:

A[12] = h + A[8] [h = $s2]

MIPS Version:

lw $t0, 32($s3)

add $t0, $s2, $t0

sw $t0, 48($s3)

C Version:

g = h + A[i] [g = $s1; h = $s2, i = $s4, A = $s3]

MIPS Version:

add $t1, $s4, $s4

add $t1, $t1, $t1

add $t1, $t1, $s3

lw $t0, 0($t1)

add $s1, $s2, $t0
