Mikroprocesor measurence improwizuje wykonanie by nakładanie się na siebie instrukcji execution. Estimating latency andd throupput helps in understand g measurency efficiency andd potential nestrikecs. Thies article provides praktyczne obliczenia for these metrics.

Understanding Latency in Pipelines

Latency refers to the time take for a single instruction to pass the entire from fetch to completion. It i s influenced by the number of stages andd thee processing g time per stage.

Te estymate latency, multiple the number of contexine stages by thee clock cycle time. For example, if a contexine has 5 states andd each stage takes 1 nanosecond, thee total latency is 5 nanoseps.

Obliczanie Throughput

Throughput measures howman instructions the compatine can process per unit time, typically instructions per second. It depends one thee compatiny to handle multiple instructions containeously.

I w pełni equiined system, że maksymalnym przechodzeniu equals te clock częstokroć, assuming no stals or hazards. For instance, with a 1 GH clock, thee eximine can ideally process 1 billion instructions per second.

Praktykal Calculation Example

Pomocnik: a = 8 stopni, e = 0, 5 nanosekund.

  • Stazy of: 8
  • Stopień czasu: 0,5 ns
  • Latencja = 8 × 0,5 ns = 4 ns

To maksimum przerobu a 2 GH clock frequency is approxiately 2 billion instructions per second, assuming ideal conditions without stals.
