a. Using MIPS conditional branch command, transform the following snippet of C code to assembly instruction. Store the value of t1 and t2 in registers $t1 and $t2 respectively.

if (t2 < t1) t1++; else t1 = t2 t1;

b. Answer the following questions based on the given MIPS code snippet.

START: addi $t1, $t1, -2 addi $t2, $t2, 5 addi $t3, $t3, -2 bne $t1, $0, START li $v0, 10 syscall i. Add MIPS instruction to the given snippet to initialize register $t1, $t2 and $t3 with immediate values as following:

$t1 = 10, $t2 = 20, $t3 = 30

ii. What is the final value in register $t1, $t2 and $t3?

iii. For code snippet above, write the equivalent C/C++ code. Assume that the register $t1, $t2 and $t3 are integer t1, t2 and t3 respectively.

c. The following snippet program is a MIPS instruction with its memory address (in hexadecimal). By referring to MIPS Reference Data, convert the underlined assembly instructions to machine code. Explain how you get the answer.
