Consider the following MIPS loop: Loop: slt $t2, $0, $t1 beq $t2, $0, Done subi $t1, $t1, 1 addi $s2, $s2, 6 j Loop Done: a) Assume that the register $t1 is initialized to the value 6. What is the value in register $s2 assuming $s2 is initially zero? b) For each of the loops above, write the equivalent C code routine. Assume that the register $s1, $s2, $t1, and $t2 are integers a, b, i, and temp, respectively. c) For the loops written in MIPS assembly above, assume that the register $t1 is initialized to the value 16. How many MIPS instructions are executed?
