CycleTimer Class Reference

Detailed Description

This is meant to be a ultra-fast interface to the hardware cycle counter, without periodic recalibration, to be even faster than absl::GetCurrentTimeNanos(). But this current implementation just uses GetCurrentTimeNanos().

Todo

(user): implement it.

GetCycles()

int64_t CycleTimer::GetCycles ( ) const

inline

This actually returns a number of nanoseconds instead of the number of CPU cycles.
