CCS/TMS320F280049: floating-point FFT

user4680685

Part Number: TMS320F280049
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

In the folder path D:\TI\c2000\C2000Ware_1_00_00_00\libraries\dsp\VCU\c28\examples\fft, I find lots of FFT examples, but they can't be used to analysis float-point datas.

In the folder path D:\TI\c2000\C2000Ware_1_00_00_00\libraries\dsp\FPU\c28\source\fft, I just find the 32-bit floating-point FFT examples, without the 128-bit or 256-bit.

Then where to find the 128-bit or 256-bit floating-point FFT examples?

Hi,

All the FFT examples are based on single precision (i.e. 32-bit) but that has no relation with 'N' in the implementation of N-point FFT. So basically, you can implement any N-point FFT using 32-bit FPU. Please go through the examples and change the value of 'N' based on your requirement.

Thanks
Himanshu

Hi Himanshu,

I misunderstood the examples, thanks for your reply.
