C674x DSPF_sp_cfftr2_dit documentation

Gaston Schelotto

Hi all,

I went back to this function used in a project some time ago and I couldn't find related documentation in the last C674x dsplib release (v1.03.00.1). I also tried to check the wiki information but I only found the DSPF_sp_fftSPxSP reference for the forward FFT kernel. This is strange because the DSPF_sp_cfftr2_dit is already implemented in the latest library. Could anyone clarify this issue?

Regards,
Gaston

Hi,

Starting from DSPLIB release 3.0.0, we will only support DSPF_sp_fftSPxSP. It is more optimized than DSPF_sp_cfftr2_dit. DSPF_sp_cfftr2_dit still exists in older dsplib releases(v1.2). If you cannot find a download link, I can send a zip file. The documentation for DSPLIB v1.2 is spru657. it is searchable on Google.

regards,

Yimin

Yimin, thanks for the clarification. I'll think about to update my routines in order to get more support for the latest FFT kernels. The only thing is about the version you have suggested and that I have not quite understand. You have pointed to v3.0.0 as I'm able to download the latest v1.3.0.1 dsplib. Am I picking a wrong link?

Gaston

Hi,

It looks like C674 DSPLIB is pointing to v1.3.0.1. If you go to C66 download page, there is a link to C674 V3.1.0. We will try to resolve this issue and consolidate the links.

regards,

Yimin
