Which version of ippsFIR could be used to map old Intel® Signal Processing Library (SPL) “nspcsbFir” function?
Either direct version or state version of ippsFIR could be used to map “nspcsbFir” function, but for performance concerns, the state version of ippsFIR should be used. Because of the following: • The FFT is used inside of ippsFIR. • The direct version is just a simple version without any structures that must be initialized. Is there any available document to help SPL migration to Intel IPP? Yes. We have provided a detailed migration document on our website. This document contains a table that lists the Intel SPL functions together with the corresponding Intel IPP functions. Even if you do not find a direct analog to the desired Intel SPL operation in the Intel IPP package, you can almost certainly find a set of Intel IPP functions that provide the desired functionality. For more information on domain library migration to Intel IPP, please refer to the Domain Library Migration FAQ. Can the Intel IPP operate on real/complex comb ination of data that have been used for FIR, IIR and CrossC
