optimised fft and ifft code needed - Murugesa pandian - Jul 5 8:38:24 2006

hi to all c54xians,
i am doing a realtime project in ofdm using c54x.the
processor misses some input samples,because of the
long processing time time codes for fft and ifft,so,i
request those who worked in this scenario to help me
with any optimised fft ,ifft algorithms,or asm
codes,or references.,etc thank u

TI's dsplib has optimized, assembly-language FFT functions:
