Crate performance_timing

Structs

• CPUInfo
  CPU information structure. Provides frequency and TSC-to-cycle scaling information.
• CriterionCycleCounter
  Custom cycle accurate measurement class for criterion
• CycleInstant
• FreqInfo
  CPU frequency information structure
• MeasureRegion
  Measure code block performance by collecting samples. It relies on the fact that objects get destroyed at the end of the block.
• MeasureSample
  Measurement sample created by MeasureRegion Shall not be created directly.

Functions

• const_cycle_loop
  Run function with known latency. Assume both sub & and ops are single cycle on all architectures. Might not behave as expected with another code running on the same phisical core.
• cycle_accurate_config
• measure_function_perf
