Question 2:

a) Provide the best equivalent sequence of MIPS instructions that could be used to implement the pseudo-instruction bgt, branch on $s0 > $s1.

bgt $s0, $s1, target You may use register $at for temporary results.

b) Provide the best equivalent sequence of MIPS instructions that could be used to implement the pseudo-instruction clear.

c) Show the single MIPS instruction or minimal sequence of instructions for this C statement:

A= b - 48;

Assume that a corresponds to register $t0 and b corresponds to register $t1

Question 3:

a) Assume $t0 holds the value 0x00011000. What is the value of $t2 after the following instructions? slt $t2, $0, $t0 bne $t2, $0, ELSE j DONE ELSE: addi $t2, $t2, 3 DONE:

b) Consider the following MIPS loop:

LOOP: slt $t2, $0, $t1 Beq $t2, $0, DONE subi $t1, $t1, 2 addi $s2, $s2, 2 j LOOP DONE:

1. Assume that the register $t1is initialized to the value 20. What is the value in register $s2 assuming $s2is initially zero?

2. For each of the loops above, write the equivalent C code routine. Assume that the registers $s1, $s2, $t1, and $t2are integers A, B,i,and temp, respectively.

3. For the loops written in MIPS assembly above, assume that the register $t1 is initialized to the value N. How many MIPS instructions are executed?
