Computer Organization and Architecture | Pipelining | Set 1 (Execution, Stages and Throughput)

To improve the performance of a CPU we have two options: 1) Improve the hardware by introducing faster circuits. 2) Arrange the hardware such that more than one operation can be performed at the same time. Since there is a limit on the speed of hardware and the cost of faster circuits is quite high, we have to adopt the 2nd option. Pipelining is a
