3. Assume $s1 = 0xefbcad97, $s2 = 0x6521fedc, calculate and $s0,$s1,$s2 or $s0,$s1,$s2 xor $s0,$s1,$s2 nor $s0,$s1,$s2 What will be content of $s0, after the execution of each instruction?

Which of the following snippets of MIPS assembly code implements the following C++ code fragment: if (x > y) z = x - y else z = y - x You may assume that x, y, and z map to the registers $t0, $t1, and $t2. ble $t0, $t1, foo sub $t2, $t0, $t1 b bar foo: sub $t2, $t1, $t0 bar: bgt $t0, $t1 sub $t2, $t0, $t1 b bar else: sub $t2, $t1, $t0 bar: ble $t0, $t1, foo sub $t2, $t0, $t1 foo: sub $t2, $t1, $t0 bgt $t0, $t1, foo sub $t2, $t0, $t1 b bar foo: sub $t2, $t1, $t0 bar:

For sub $rd, $rs, $rtReg[rd] = Reg[rs] + Reg[rt] - Which resources (blocks) perform a useful function for the given instructions? - Use the following diagram for each instruction and trace its flow(use pen or highlighter) for the execution of that instruction. - List the units that are used for each instruction. (I mainly need help with tracing, please and thank you)

Which of the following instructions JMP, CMP, JZ, and JNZ can transfer control to another point in a program uncondiotionally? a) The unconditional instruction is JZ.b) The unconditional instruction is CMP.c) The unconditional instruction is JNZ.d) The unconditional instruction is JMP.
