Consider the operation of a machine with the data path of Figure 2.2 in your Textbook. Suppose that loading ALU input registers takes 2 nsec, running the ALU take 8 nsec, and storing the result back in the register scratchpad takes 2 nsec. What is the maximum number of MIPS this machine is capable of in the absence of pipelining?

On computer 1, all instruction take 20 nsec to execute. On computer 2, they all take 10 nsec to execute. Can you say for certain that computer 2 is faster? Discuss.
