chrono-benchmark

Small C++ class for chrono based benchmarks / time measurements

Example

Example code for the use of the benchmark class:

#include "benchmark.h"

void main() {

  benchmark time;

  time.start();

  for (uint32_t i = 0; i < 1000000; i++) 
  {
    // do nothing, just waste time
  }

  time.end();

  std::cout << "Consumed time in milliseocnds: " << time.get_ms();

}

Methods

void start()

Start the clock of the benchmark instance

void end()

End the clock of the benchmark and calculate the ellapsed time between start() and end() call.

µs_t get_µs()

Get the ellapsed time as microseconds

ms_t get_ms()

Get the ellapsed time as milliseconds

sec_t get_sec()

Get the ellapsed time as seconds

Constants

constexpr long double c_msfactor = 1000.0;

Conversion factor from microseconds to milliseconds

constexpr long double c_secFactor = 1000.0 * c_msfactor;

Conversion factor from microseconds to seconds

Types

New defined data types and their basic type:

Name	Type
µs_t	long double
ms_t	long double
sec_t	long double
time_point_t	std::chrono::time_point<std::chrono::steady_clock>
