* DESCRIPTION:  This include file sets the FFT size for the 'C54x Real FFT code *
*               Note that the Real FFT size (i.e. the number of points in the   *
*               original real input sequence) is 2N; whereas the FFT size is    *
*               the number of complex points formed by packing the real inputs, *
*               which is N.  For example, for a 256-pt Real FFT, K_FFT_SIZE     *
*               should be set to 128 and K_LOGN should be set to 7.             *
*                                                                               *
