Part 2: Use the single cycle model to answer the following questions.

1. Can the sltiu instruction execute correctly with this data path? Why or why not?

2. A nori instruction is being proposed. Can this new instruction execute correctly with this data path? Why or why not?

3. Determine the control values in the table below for the instructions. If it cannot be determined, leave it blank.

4. Describe the changes needed to the single cycle data path to support the jr instruction.

5. The following instruction is to be executed: sw $t1, 4($t2). The instruction is located at 0x00401000. Assume that #t1 holds a -1 and $t2 holds 0x10010010 Give the values of the following:

i. Output of sign-extended

ii. Output of shift left 2

iii. Inputs to ALU control

iv. Output from MUX before registers

v. Output to MUX before ALU

vi. Output from ALU

vii. Output from adder at top left

viii. Output from adder at top right
