No! – Speed: cycle time must be long enough for the most complex instruction to complete – But the average instruction needs less time – Cost: functional units (e.g. adders) …

Does CPU pipelining always imply a multicycle datapath?

WebEngineering. Electrical Engineering. Electrical Engineering questions and answers. Suppose the multicycle RISC-V processor has the component delays given below. Ben designs a new register file that has 40% less power but twice as much delay. Should she switch to the slower but lower power register file for her multicycle processor design? WebHas an internal state. Output depends on the current state (and maybe the inputs). Next state depends on the current state and the inputs. Each state will take 1 cycle. First two states same for every instruction, next state depends on opcode. After completing the final step for an instruction, the FSM returns to the initial state. ezake
