FFT routines for DSP563xx

Started by C_Kessell December 6, 2001
Is anyone aware of any up-to-date FFT application notes or code from
Motorola for the DSP563xx family? The Motorola web site is now almost
useless for such things (even the ancient APR4/D application note
"Implementation of Fast Fourier Transforms on Motorola's DSPs" seems to be
no longer listed) - compared to the information available on the Texas
Instruments and Analog Devices sites it's quite embarrassing.

Poking around the web has only yielded some poorly documented 10-year-old
code for the 56000. Although these routines do work OK, I feel sure that
newer, more optimised routines should be possible for the latest DSPs with
larger on-chips memories etc.
