Suppose an instruction takes four cycles to execute in a nonpipelined CPU: one cycle to fetch the instruction, one cycle to decode the instruction, one cycle to perform the ALU operation, and one cycle to store the result. In a CPU with a four-stage pipeline, that instruction still takes four cycles to execute, so how can we say the pipeline speeds up the execution of the program?

1. Explain the steps in the fetch–decode–execute cycle. Your explanation should include what is happening in the various registers. 2. Explain why, in MARIE, the MAR is only 12 bits wide and the AC is 16 bits wide. (Hint: Consider the difference between data and addresses.)

Assume that as an average, each stage requires three micro- operations to complete. Also, assume that the control memory is N bits wide (i.e., control field bits + address selection field bits + address-one bits + address-two bits N bits).
