IPP 8.1 - ippsFIRGetStateSize_32f

Hello,

I have a question about FIR filtering functionality. When I ask for the FIR state buffer size using method below:

ippsFIRGetStateSize_32f( int tapsLen, int *pBufferSize )

I get unusually huge values e. g. 17792 for tapsLen=1. Is this expected? From what I understood from documentation the FIR state structure contains taps values and delay buffer. I see no reason why this should be this big.
