A single cycle MIPS processor introduced in the textbook executes the

instruction lw $t3, 0xFFF4($t0) or below the figure.

You need to answer following questions( and need to write at least two

pages):

1. draw the complete datapath and control signals needed to execute this instruction.

1. explain how the datapath works

2. explain how the controller works

3. explain what values the control signals take

4. what type of instruction it is

5. need to explain how to compute the cycle time for this processor and

give a formular.
