Use the MARS IDE for the following questions. Submit your MIPS code as separate files (one per question). Files should be self-contained and runnable. For #2, submit a screenshot of the console output with your completed assignment. [10] Consider the following MIPS procedure. Note that $a0 and $a1 are input arguments and both initially contain the integers a and b, respectively. Assume that SvO is used for the output. 1. add $t0, Szero, zero beq $a1, $zero, finish add $t0, $t0, a0 addi al, $al, -1 j loop loop: # ? finish: addi $to, $t0, 100 add $v0, $t0, Szero [5] Add comments to describe what each line in assembly is doing, then summarize in one sentence what the whole program accomplishes. a. b. [5] This code can be optimized, i.e. written using fewer instructions. Re-write the code using at most 3 instructions
