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.
