8. Fetch takes 300 ps, decode 250 ps, execute is 290 ps, memory is 310 ps,...
A 5-Stage pipeline is composed
of the following stages Instruction Fetch (IF), Decode (DE),
Execute (EX), Memory Access (ME) and Register Write-back (WB).
Assume the pipeline does not have a branch prediction unit, does
not have superscalar support and does not support out of order
execution. Assume that all memory accesses are in the L1 cache and
therefore do not introduce any stalls. Show a pipeline diagram that
shows the execution of each stage for the assembly code below. Also...
(Pipelining 20%) The 5 stages of a processor have the following latencies: Fetch Decode Execute Memory Write-back 250 350ps 300ps 500ps 80ps a. If the processor is non-pipelined: what is the clock cycle time for the processor? What is the latency of an R-type instruction in the processor? b. If the processor is pipelined: What is the clock cycle time for the processor? What is the latency of an R-type instruction in the processor? C. If you could split one...
Suppose the times required by each of the functional units of a MIPS processor to do their work are: Instruction Memory: 400 ps Data Memory: 400 ps ALU: 300 ps Register file: 200 ps lgnoring the overhead introduced by the pipeline registers, what is the maximum speedup achieved by the pipelined processor with fetch, decode, execute, memory and write back stages vis-a-vis the single-cycle processor? Give your answer to two decimal places.
A particular (fictional) CPU has the following internal units and timings: 1. IFD: Instruction fetch + decode : 160 ps 2. RR: Register read 80 ps 3. ALU: 240 ps 4. MA : memory access: 160 ps (assuming cache) 5. RW : register write : 80 ps There are 5 basic instruction types: 1. LOAD : IFD+RR+ALU+MA+RW 720 ps 2. STORE: IFD+RR+ALU+MA : 640 ps 3. ARITHMETIC: IFD+RR+ALU+RW : 560 4. BRANCH: IFD+RR+ALU : 480 ps 5. MEMOP: IFD+RR+MA+ALU+MA :...
Group Project 1 The Micro-1 Processor Simulation <Micro-1 Computer> Here's the organization of a computer equipped with a Micro-1 processor Memory contains an array of integer cells: int cell[] = new int[CAP]; where CAP is the capacity of memory. Initially this is set to 256. Internally, the Micro-1 processor is equipped with eight 32-bit data/address registers and two 32 bit control registers: PC, the program counter, contains the address of the next instruction to execute. IR, the instruction register, contains...
