CPU Design for Multiple Clock Cycles per instruction {CPI > 1}

CPU Design for Multiple Clock Cycles per instruction {CPI > 1}. Be able to explain how an instruction is executed and the concept of datapaths and control. Where we are headed. Single Cycle Problems: clock cycle determined by instruction that takes the longest time

Multicycle Approach

Multicycle Approach. Break up the instructions into steps each step takes one clock cycle balance the amount of work to be done in each step/cycle so that they are about equal restrict each cycle to use at most once each major functional unit so that such units do not have to be replicated
