Ipp complex/float multi-rate FIR filter usage

Hi there,

I am using ippCore 2018.0.1 (r56998) and tried to initialize the multi-rate FIR filter specification structure for the Ipp32fc (complex) source/destination vectors and the real Ipp32f (float) filter coefficients, but ippsFIRMRInit function generates error about real float filter coefficients type. How can I configure multi-rate FIR filter for processing complex data with real float filter coefficients?

Regards,
Vlad

Hi Vlad.

As workaround you can create temporal complex coefficient vector and zero its complex part. But may be we add special optimization of this case in next IPP releases.

Thanks.

Hi Andrey,

It would be nice to have the special optimization of this case in next IPP releases.

Thanks,

Hi Andrey,

Please let me know when the special optimization of this case is available to use.

Thanks,
