help please

2. (Chapter 2.7) Consider the following MIPS loop: Loop: slt $t2. SOSt1 beq St2, SO, Done subi $t1,$t1, 1 addi j Done: $s2. Ss2, 4 Loop a) Assume that the register $t1 is initialized to the value 6. What is the value in register $s2 assuming $s2 is initially zero? (2 points) b) For each of the loops above, write the equivalent C code routine. Assume that the register Ssl. Ss2, $t1, and $12 are integers a, b, i, and temp, respectively. (2 points) c) For the loops written in MIPS assembly above, assume that the register $t1 is initialized to the value 9. How many MIPS instructions are executed? (2 points) 3. (chapter 3.2) Assume 186 and 99 are signed 8 bit decimal integers stored in sign-magnitude format. Calculate 186 -99. Is there overflow, underllow, or neither? (3 points) 1 omad hit decimal into one in u s
