/*
* functions for counting operations
*
* These functions, and the ones in basic_op.h, makes it possible to measure
* the wMOPS of a codec.
*
* All functions in this file, and in basic_op.h, uppdates a structure so that
* it will be possible the see how many calls to add, mul mulAdd ... that the
* code made, and estimate the wMOPS (and MIPS) for a sertain part of code
*
* It is also possible to measure the wMOPS separatly for different parts
* of the codec.
*
* This is done by creating a counter group (getCounterId) for each part of the
* code that one wants a separte measure for. Before a part of the code
* is executed a call to the "setCounter" function is needed to identify
* which counter group to use.
*
* Currently there is a limit of 255 different counter groups.
*
* In the end of this file there is a pice of code illustration how the
* functions can be used.
