#define | FFTC_MAX_NUM_BUTTERFLY_STAGES (7) |
The Maximum number of butterfly stages supported. | |
#define | FFTC_NUM_INTERNAL_BUFFERS (3) |
The number of internal buffers used by FFTC for simultaneous input, output and calculation operations. A complete FFTC Engine status snapshot can hence be obtained by putting together the status of all the three buffers. | |
#define | FFTC_MAX_NUM_BLOCKS (128) |
The maximum number of FFT block sizes that can be specified to the FFTC engine hardware. | |
#define | FFTC_MAX_NUM_TXQUEUES (4) |
The number of Transmit queues dedicated for FFTC from the CPPI-Queue Manager (QM). | |
#define | FFTC_DEF_CPPI_QUEUE_NUM (0x3FFF) |
Default value for CPPI Destination queue number. | |
#define | FFTC_DEF_DFT_SIZE (0x3F) |
Default DFT size. | |
#define | FFTC_MAX_NUM_PS_WORDS (4) |
Maximum number of PS Info words (32 bit words ) supported by the FFTC engine. |
#define FFTC_DEF_CPPI_QUEUE_NUM (0x3FFF) |
Default value for CPPI Destination queue number.
Configure the destination CPPI queue number for any given FFTC queue as this value, and the default CPPI queue number from the CPPI DMA channel configuration is used.
#define FFTC_DEF_DFT_SIZE (0x3F) |
Default DFT size.
Configure the 'DFT_size' field of the Queue X Control Register to this value to indicate to the engine to use DFT Size list to pick up block sizes.
