/* * 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.
