ippsFIRSRGetSize results in extremely large bufSize

$

Hi,

Using IPPS version 2018 update 3 and 2019 update 1, both with the same result for the following call.

ippsFIRSRGetSize (TAPS_LEN,  ipp32f ,  &specSize,  &bufSize );

No matter what size TAPS_LEN the bufSize is >32k. This is an extremely large buffer for e.g. a 4 tap FIR filter. Both specSize and bufSize is of type int as documentation says. The general purpose IIR filter of the same order takes up much less memory.

Is this an error in IPPS? Or what could the reason be?
