Multi-cycle datapath. Multi-cycle implementaion: break up instructions into separate steps. Each step takes a single clock cycle. Each functional unit can be used more than once in an instruction, as long as it is used in different clock cycles. Reduces amount of hardware needed. Reduces average instruction time.
4 Mar 2010 Assemble the datapath segments, add control lines, and multiplexors. • Single cycle design – fetch, decode and execute each instructions in one clock cycle. – no datapath resource can be used more than once per instruction, so some must be duplicated (e.g., separate. Instruction Memory and Data
The multi-cycle version. Note that we have eliminated two adders, and used only one memory unit (so it is Princeton architecture) that contains both instructions and data. It is not essential to have a single memory unit, but it shows an alternative design of the datapath.
Our program consists of executing N instructions. ? Our processor needs CPI cycles for each instruction. ? The maximum clock speed of the processor is f, and the clock period is therefore T="1"/f. ? Our program will execute in. N x CPI x (1/f) = N x CPI x T seconds

These slides are available at: and ALU, since we assume that they introduce the most significant delays during execution of instructions. ? We assume all other delays in the datapath negligible.
