Cpu time
Hi Experts,

If a thread running on CPU needs some data from RAM (from near or far RAM) it requests the data (this moment of time is t0) and gets it in moment of time in t1, and continues his work.

Between t0 and t1, while data is transferring from RAM, the thread is goes out from CPU? Is the time between t0 and t1 included or excluded from CPU time?

Thanks

NAME

       mlib_ImageMoment2 - second moment

SYNOPSIS

       cc [ flag... ] file... -lmlib [ library... ]
       #include <mlib.h>

       mlib_status mlib_ImageMoment2(mlib_d64 *moment, const mlib_image *img);

DESCRIPTION

       The mlib_ImageMoment2() function computes the second moment of each channel in an image.

       It uses the following equation:

		       1     w-1 h-1

		      w*h    x=0 y=0

PARAMETERS

       The function takes the following arguments:

       moment	 Pointer to moment array, where length is the number of channels in the image.

       img	 Pointer to an image.

RETURN VALUES

       The function returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
