Hello Michael,
Check out the DSPLIB routines for vectors:
DSPLIB: http://www.ti.com/tool/sprc100
short maxidx (DATA *x, ushort ng, ushort ng_size) Index for maximum magnitude in a vector
short maxidx34 (DATA *x, ushort nx) Index of the maximum…
Hi,
Have you reviewed the Chapter 2 - FFT Implementation on the TMS320C5535 DSP in the TRM ( SPRUH87 )?
It includes details about input and output data formats ( 2.5.1 Data Types & 2.5.2.2 HWAFFT Parameters ) and calling FFT functions from ROM ( 2…
Tommy,
The website is still missing the DSPLIB download, but it will be fixed very soon.
Until then, use this link to download the sprc100.zip file: http://www.ti.com/lit/zip/sprc100
Best Regards, Mark
Deepak,
Download and install " DSPLIB-C55X — C55x DSP Library (DSPLIB) " from https://www.ti.com/tool/SPRC100
You may get it.

Yilmaz,
TI's DSPLib has optimized FFT routines, and benchmarks. You could use those without HWAFFT, and then assume a times 4 speedup with it. See:

Other Parts Discussed in Thread: SPRC100 , TMS320C5515 Hi all,
1. I would like to do fft and then ifft operations on some real data taken from the C5515 codec used on the ezDSP c5515 USB stick.
So my audio data is 16bit. Ideally I would like the fft…
Check out the C5000 Teaching ROM. It shows wavelets and IIR filters, which should kickstart your development.
