Crate performance_timing Copy item path Source 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. 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
