Limitations of single cycle cpu
Nettet15. jun. 2014 · Single-cycle: CPU time = 1 * 800 ps * 10 instr. = 8000 ps. Pipeline: CPI = 21 cycles / 10 instr. = 2.1 cycles per instruction. CPU time = 2.1 * 200 ps * 10 = 4200 ps. CPU time single-cycle / CPU time pipeline = 8000/4200 = 1.9, so the pipeline code runs 1.9 faster. But I was said, I have to work with clock cycles and not with the time -- "It ...

Limitations of Memory System Performance • Memory system, and not processor speed, is often the bottleneck for many applications. • Memory system performance is largely captured by two parameters, latency and bandwidth. • Latency is the time from the issue of a memory request to the time the data is available at the … NettetWith a single-execution-unit processor, the best CPI attainable is 1. However, with a multiple-execution-unit processor, one may achieve even better CPI values (CPI < 1). …
