TMS320C6678: 128 pts SP-FP FFT computation time

Florian Grützmacher

Part Number: TMS320C6678

Hi,

in the Application Report about DSP Benchmarking i found in a table the computation time for a 256 pts and 1K pts SP floating point FFT performed on a C66x core.

Is there also a benchmark for a 128 pts FFT available?

Kind regards,
Florian

Hi Florian,

The only available benchmarking is this:
www.ti.com/.../sprac87.pdf
www.ti.com/.../sprac13.pdf

There are no other documents, that are publicly available.

Best Regards,
Yordan

Core benchmarking for 256 point and 1K for C66x aand C674x and ARM cores is provided on the CORE benchmarking page on ti.com:
www.ti.com/.../core-benchmarks.html

please use this for evaluation and refer to the application notes yordan pointed to if you want to know what was implemented to gather those benchmarks:

Rahul
