1. (10 points) Add comments to the following MIPS code and describe in one sentence what it computes. Assume that Sa0 is used for the input and initially contains n, a positive integer. Assume that $v0 is used for the output. begin: addi $10, $zero, 0 addi St1, Szero, 1 loop: slt $t2, Sa0, St1 bne $t2, $zero, finish add $10, $10, $t1 addi $t1, $tl, 2 j loop $v0, $10, $zero finish: add 2. (10 points) Write MIPS code for the following high-level language program fragment: Loop: g g+A[i]; // Assume g is in $s1; i is in Ss3; base address of A is in $s5 i=i+j; // Assume j is in register $s4; h is in register $s2 if (i!=h) go to Loop
