Function Documentation

float throughput	(	float	runtime,
		int	pixels
	)

Compute the throughput in Gibipixels = 2^30 pixels.

Parameters

runtime	running time in milliseconds
pixels	number of pixels

Returns

throughput in MiP/s

unsigned long millisecond_timer

(

void

)

Millisecond-precision timer function.

Returns

Clock value in milliseconds

This routine implements a timer with millisecond precision. In order to obtain timing at high resolution, platform-specific functions are needed:

• On Windows systems, the GetSystemTime function is used.
• On Mac and POSIX systems, the gettimeofday function is used.

Preprocessor symbols are checked in attempt to detect whether the platform is POSIX or Windows or Mac and defines millisecond_timer() accordingly.
