AWR1843: dsplib function to support 384-pt DFT

Adam Yao94020

Part Number: AWR1843

Hi champion,
I find FFT function DSP_fft16x16 in C:\ti\dsplib_c64Px_3_4_0_0 and C:\ti\dsplib_c66x_3_4_0_0 can only support radix-2 and radix-4 DFT.

Do we have function in dsplib to support 384 point FFT?

Thanks,
Adam

Hi,

Since 384 is not a power of 2 or 4 we don't have an optimized implementation of this FFT size.

Customer can use a standard C implementation of FFT that will work for all sizes.

Thank you

Cesar
