Understanding Latency in Pipelines

Latency refers to the time takn for a single instruction to pass regulgh the entire complition e from fetch to completion. It i influenced by the number of stages and the processing time pre stage.

To estimate latency, multi tha number of dicine stages by the clock cycte time. For example, if a bracine has 5 stages and each stage takes 1 nanosomond, the totál latency is 5 nanosoms.

Calculating Throughput

Throughput measures how many instructions the dicinine can proces pre unt time, typically instructions persecond. It deposs the e 's ability to handle multiple inities thermaneously.

A teljes körű intuined system, the maximum through equals the clock custancy, assumming no stall or hazards. For instance, with a 1 Ghz clock, the preferenine can ideally proces 1 billion instructions per second.

Practical Calculation Example

Suppose a therine has 8 stages, each taking 0.5 nanosects. The latency for a single instruction i:

  • Number of stages: 8
  • Time per stage: 0.5 ns
  • Latency = 8 × 0.5 ns = 4 ns

Ez a maximális át a 2 GHz clock gyakori i megközelíti 2 billion oktatás per support, assumming ideel feltételeks out stands.
