Convert the following MIPS instructions into Machine Code in

Convert the following MIPS instructions into Machine Code instructions. Assume the first instruction starts at memory address 20000

slt $t1, $s1, $s0

beq $s1, $s2, L1

beq $t1, $zer0, L2

j Exit

L1: add $s1, $s1, $s1

j Exit

L2: addi $s1, $s1, 1

Exit:

Solution

Line 1: 0x00020000 [slt $t1 $s1 $s0 => R(op:0(slt) rs:17(s1) rt:16(s0) rd:9(t1) sh:0 func:42)]
