Question
(c) The process of fetching the next instruction when the present instruction is being executed is termed
instruction pipelining. With an instruction pipeline, having separate instruction and data memories
allows the CPU to do more at the same time. A typical instruction has the following five stages:
i) f- fetch instruction from memory
ii) r- decode instruction, and read register operands
iii) a - execute instruction using ALU (arithmetic logic unit), or calculate address
iv) d - access data memory (load or store)
v) w – write result back to register
Using a diagram, illustrate how the pipelining process achieves a perfomance of one instruction
per clock cycle. How does caching help in microprocessors used for general-purpose computing?
