38.8.1. Real Time Latency Concerns
This section presents an overview of interrupt latency, the elements that combine to determine interrupt latency, and methods for measuring it. The following elements comprise interrupt latency:
- Pipeline latency
- Cause latency
- Selection latency
- Funnel latency
- Compiler-related latency
This section summarizes each element of latency and describes how to measure latency. The accompanying example designs use the performance counter core to capture all of the timing measurements. Performance counter core usage is described in “Latency Measurement with the Performance Counter”.
