1.Consider the following java code. Write equivalent MIPS assembly code. Assume that the compiler keep values of the variables A and B in the registers $t0 and $t1 respectively.

if ( A > B) A = A B; else B = B - A

2. What is the RTL description of the instruction JAL sub? [note that, the order is important. &sub stands for the address of the label sub]

R[ra] PC + 4 , PC &sub

PC &sub, R[ra] PC + 4

R[ra] = &sub, PC PC + 4

R [ra] PC , PC &sub

3. Consider the following MIPS program. After execution, what will be the value in $t0 when PC points the label END?

addi $t0, $0, 5 addi $a0, $t0, $0 jal TEST move $t0, $v0 j END TEST: add $v0, $a0, $a0 jr ra END:

a. 5

b. 10

c. 0

d. Cannot be determined
