TDA4AEN-Q1: Few Question About DSP

Expert 6500 points

Part Number: TDA4AEN-Q1
Other Parts Discussed in Thread: FFTLIB

Dear Expert.

Here are some question about TDA4 DSP, I am not familar it, so forward customer's question and post here, need your comment.

Q1: In the CCS compiler folders below,
C:\ti\ccs2040\ccs\tools\compiler\ti-cgt-c7000_5.0.1.LTS\host_emulation\include\c7524-MMA2_256, we observe a header file named c6x_migration.h, which is like a middle layer that converts C6x APIs to C7x ones. It seems to imply C6x-to-C7x migration is supported.
If we developed our application with C6x libraries, would it be possible to migrate it with C7x libraries with any change in the application?

Q2 : Does C7x FFTLIB supports radix-3, mixed-radix, or required non-power-of-two Doppler FFT sizes?

Q3 : Does C7x FFTLIB supports complex-to-complex FFTLIB twiddle-factor generation options?

 

Thank You.

Gibbs

    If your intention is to migrate C66x code to C7x, please follow the steps outlined in the FAQ.

    No. 

    Radix-3 -> No

    non-power-of-two -> No

    mixed-rdix -> only with power of 2

    Yes. All FFT-related details are available here; please have a look. How to Use FFTLIB? 

    e.g: FFTLIB_fft1d_i16sc_c16sc_o16sc
