Part Number: TMS320F28377S

Hi，

About example 2837X_vcu2_cfft_512 input/output data, ask a few questions。

1, What is input data format? is it raal+imaginary? and data is Q format?

2, What is output data format? is it Amplitude or Phase? What is the data strictire?

Thanks。

Li Darren,

The 1024-point input buffer to the CFFT represents real data in Q15 format. i.e. signed 16-bit integer.

The 1024-point output buffer contains two 512-point partitions representing real and imaginary data, also in Q15 format.

Regards,

Richard
