Functions for Packed Data Multiplication
The functions described in this section perform the element-wise complex multiplication of vectors stored in Pack or Perm formats. These functions are used with the function ippsFFTFwd and ippsFFTInv to perform fast convolution on real signals.
The standard vector multiplication function ippsMul can not be used to multiply Pack or Perm format vectors because:
- Two real samples are stored in Pack format.
- The Perm format might not pair the real parts of a signal with their corresponding imaginary parts.
The vectors stored in CCS format can be multiplied using the standard function for complex data multiplication.
- MulPack
Multiply the elements of two vectors stored in Pack format. - MulPerm
Multiply the elements of two vectors stored in Perm format. - MulPackConj
Multiplies elements of a vector by the elements of a complex conjugate vector stored in Pack format.
