Question 3 (10 points) Convert the following MIPS assembly code into machine language. Write the instruction in hexadecimal. The opcode for sw 43 (101011). sw St1, -4(St3) Question 4 (10 points) Consider the following MIPS assembly code: addi $s3, $0, 5 addi $s1, S0, 3 addi Ss1, $s1, 2 beq Ss3, Ssl, target addi Ss1, Ss1, 1 target: add Ss3, Ss1, Ssl a. After running the code, what is the value of Ss3? b. If the memory address of the first instruction (addi $s3, S0, 5) is 0x00400000, what is the address of the third instruction in the code (addi Ssl, Ss1, 2

Answer 1

sw $t, offset($s)

1010 11ss ssst tttt iiii iiii iiii iiii

our instruction:
sw $t1, -4($t3)

$t is $t1 which is 9 (ttttt is 01001)
$s is $t3 which is 11(sssss is 01011)
4 in binary is 0000 0000 0000 0100
-4 in binary is 1111 1111 1111 1100 which is FFFC

sw $t1, -4($t3) is
1010 1101 0110 1001 1111 1111 1111 1100 => 0xAD69FFFC
