Hello, everyone. I hope someone help me.
The time to calculate FFT of 1024 point consume 8 ms with tms28335, which is too slow. The routiune presented is written in c. What's wrong with me? How to resolve it?

Hi, but there still exist another problem.
I run example( float an complex: C:\ti\controlSUITE\libs\dsp\FPU\v1_40_00_00\examples_ccsv5\2833x_cfft), loading input buffer data into matlab, and calculate FFT. When I compare result between matlab and example. They are differrent somewhat. The upper graph is calculated in matlab, the other is in example, which have some spikes. Please help me.
Thank a lot.

Hello, everyone.
The problem has been solved. The file used by my companion is a old file, not in ContolSuite. I give him a severe beating. I have been confusing why they aren't in accordance, Ti is a big company. The answer is this.
But Ti also need Technical Support Engineer to help client.
