I'm currently investigating IPP 8 and have a few problems with the biquad IIR support:
- ippsIIRInitAlloc is now deprecated, fine by me, we can allocate manually. However I need to be able to changes the IIR taps WITHOUT changing the filter state. ippsIIRInit seems to destroy the delay line, which makes it unusable. So the only way to change taps without using deprecated functions is to copy the delay line and set it back with ippsIIRInit, which is unacceptable. So what am I missing?
