Detailed Description

Fftc_DestQRegCfg.

Structure to specify/hold the CPPI Destination queue information stored in the FFTC hardware's Queue X Destination Queue Register for a given FFTC queue.


Field Documentation

Boolean Flag, set to 1 to enable FFT shift at input (reverse left/right halves)

Corresponds to the 'FFT_shift_left_right_input' bit field of the FFTC Queue x Destination Queue Register.

Boolean Flag, set to 1 to enable FFT shift at output (reverse left/right halves)

Corresponds to the 'FFT_shift_left_right_output' bit field of the FFTC Queue x Destination Queue Register.

CPPI Destination queue number where the FFT computation result needs to be put.

Corresponds to 'dest_queue' bit field in the FFTC Queue X Destination Queue Register.

MUST be set to '0x3FFF' if using FFTC higher layer APIs to configure queue.

Input shift value to use.

Corresponds to the 'FFT_variable_shift_input' bitfield of the FFTC Queue x Scaling & Shifting Register.
