1 Inf2C - Computer Systems Lecture 12 Processor Design Multi-Cycle Boris Grot School of Informatics University of Edinburgh
2 Previous lecture: single-cycle processor Inf2C Computer Systems Boris Grot 3
3 Question: which instruction takes the most time to complete in a single-cycle processor? Inf2C Computer Systems Boris Grot 4
4 Motivating a multi-cycle processor Aren t single cycle processors good enough? 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) cannot be re-used within one instruction s execution Inf2C Computer Systems Boris Grot 5
5 Measuring processor speed Execution time is: instruction count cycles per instruction cycle time Programmer, compiler, ISA Processor design Inf2C Computer Systems Boris Grot 6
6 Multi-cycle processor: Basic idea Break up the execution of each instruction into multiple cycles Ensure that the actions performed within each cycle are generic i.e., common to many instructions Reuse a common set of datapath and control components across cycles End result: no instruction takes more time than necessary Inf2C Computer Systems Boris Grot 7
7 Multi-cycle processor: Datapath building blocks One memory Shared between instructions and data Common interface Registers Read early in instruction execution Written late (if ever) in inst. execution One ALU All PC calculations (conditional & unconditional) All arithmetic (inc. branch condition evaluation) Inf2C Computer Systems Boris Grot 8
8 Multi-cycle processor: Basic operation Each instruction takes multiple cycles to execute Each cycle, at least one basic function performed (e.g., Fetch or Read Registers) Multiple functions can be performed in one cycle if they use different functional units E.g., Fetch à memory, PC+4 à ALU Example execution: SW cycle 1: Fetch (access memory) cycle 2: Read registers cycle 3: Compute address (use ALU) cycle 4: Perform store (access memory) Same memory, accessed in different cycles Inf2C Computer Systems Boris Grot 9
9 Multi-cycle processor: Details Cycle time determined by the propagation delay through the slowest functional unit Number of cycles varies for different instructions At the end of each cycle, data required in subsequent cycles must be stored somewhere Data used by subsequent instructions stored in memory and registers à same as single-cycle processor Data for the current instruction stored in special registers not visible to the programmer à NEW! Inf2C Computer Systems Boris Grot 10
10 Multi-cycle datapath (overview) One memory for both Instruction & Data One ALU for all arithmetic Inf2C Computer Systems Boris Grot 11

Select ALU input A (PC or A register) Read the memory (could be for instruction fetch or data load) Write the memory Select the source of data to be written to the register file (ALUout or MDR) Select the source of the address for the memory unit (PC or ALUout) Write the IR with output of the memory unit New in multi-cycle processor Write the PC register (source controlled by PCSource) Write the PC if Zero output from the ALU is active Inf2C Computer Systems Boris Grot 19

20 How to design the control The control unit of a multicycle processor is an FSM For a given instruction type, determines the sequence of control signals on a cycle-by-cycle basis On a given cycle: outputs the control signals and next FSM state Inf2C Computer Systems Boris Grot 21

CSE 30321 Lecture 10-11 In Class Example Handout Question 1: First, we briefly review the notion of a clock cycle (CC). Generally speaking a CC is the amount of time required for (i) a set of inputs to
Multicycle conclusion
Multicycle conclusion The last few lectures covered a lot of material! We introduced a multicycle datapath, where different instructions take different numbers of cycles to execute. A multicycle unit is
