Classes | |
| struct | ArchIntervalTimer |
| A simple timer class for measuring an interval of time using the ArchTickTimer facilities. More... | |
Functions | |
| uint64_t | ArchGetTickTime () |
| Return the current time in system-dependent units. More... | |
| uint64_t | ArchGetStartTickTime () |
| Get a "start" tick time for measuring an interval of time, followed by a later call to ArchGetStopTickTime(). More... | |
| uint64_t | ArchGetStopTickTime () |
| Get a "stop" tick time for measuring an interval of time. More... | |
| ARCH_API uint64_t | ArchGetTickQuantum () |
| Return the tick time resolution. More... | |
| ARCH_API uint64_t | ArchGetIntervalTimerTickOverhead () |
| Return the ticks taken to record an interval of time with ArchIntervalTimer, as measured at startup time. More... | |
| ARCH_API int64_t | ArchTicksToNanoseconds (uint64_t nTicks) |
Convert a duration measured in "ticks", as returned by ArchGetTickTime(), to nanoseconds. More... | |
| ARCH_API double | ArchTicksToSeconds (uint64_t nTicks) |
Convert a duration measured in "ticks", as returned by ArchGetTickTime(), to seconds. More... | |
| ARCH_API uint64_t | ArchSecondsToTicks (double seconds) |
Convert a duration in seconds to "ticks", as returned by ArchGetTickTime(). More... | |
| ARCH_API double | ArchGetNanosecondsPerTick () |
| Get nanoseconds per tick. More... | |
| template<class Fn > | |
| uint64_t | ArchMeasureExecutionTime (Fn const &fn, uint64_t maxMicroSeconds=10000, bool *reachedConsensus=nullptr) |
Run fn repeatedly attempting to determine a consensus fastest execution time with low noise, for up to maxMicroseconds, then return the consensus fastest execution time. More... | |
