Hi all;We have a fairly complex algorithm running on about 6 Mbytes of data under Windows 7 64 bit using the Intel ipp libraries throughout. As part of optimization, the profiler consitently showsippiZigzagInv8x8_16s_C1 as the most expensive function interms of time. We do not call this directly but it appears to get called after a call toippiSqr_32f_C1IR orippiMulC_32f_C1IR.What is this function and is there any way of reducing the approximately 40% of our process time by either eliminating or replacing it? All our applications are 64 bit.
