For these problems, the table holds MIPS assembly code fragments. You will be asked to evaluate each of the code fragments, familiarizing you with the different MIPS branch instructions.

For the loops written in MIPS assembly above, assume that the register $t1 is initialized to the value N. How many MIPS instructions are executed?

a. b. LOOP: addi $s2, $s2, 2 subi $t1, $t1, 1 bne $t1, $0. LOOP DONE: LOOP: DONE: $t1 slt $t2, $0, beq $t2, $0, DONE subi $t1, $t1, 1 addi $s2, $s2, 2 j LOOP
