TMS320F280025: FFT and AC harmonic calculation

Part Number: TMS320F280025
Other Parts Discussed in Thread: C2000WARE

Dear Champs,

I am asking this for our customer.

1) FFT computation

F28002x does not have VCU like that on F28004x.

The user wonders if there is any hardware accelerators for FFT?

If not, is the software library the only solution we provide?

C:\TI\c2000\C2000Ware_3_04_00_00\libraries\dsp\FPU\c28

2) AC input harmonic and distortion calculation

The FFT is used for AC input voltage harmonic calculation.

Other than FFT, do we have any hardware accelerator or corresponding library or codes for AC harmonic and distortion calculation?

    Yes. You can use the FPU and the TMU to accelerate FFT calculations along with the software library.

    No. We do not offer libraries or sample code for THD calculation.
