Detailed Description

dopplerProc DPU HWA configuration parameters

The structure is used to hold the HWA configuration parameters for the Doppler Processing DPU

Data Fields
DPU_Aoa2dProc_FFTWindowCfg	dopplerWindow

DPU_Aoa2dProc_FFTWindowCfg	angleWindow

uint8_t	firstStageScaling
	Indicates if HWA should enable butterfly scaling (divide by 2) of the first radix-2 stage. Depending on the window definition, user may want to skip the first stage scaling in order to avoid signal degradation. Options are: Disable first stage scaling: firstStageScaling = DPU_AOA2DPROC_FIRST_SCALING_DISABLED Enable first stage scaling: firstStageScaling = DPU_AOA2DPROC_FIRST_SCALING_ENABLED Note: All other butterfly stages have the scaling enabled. This option applies only for the first stage. . More...

uint8_t	numParamSets
	Number of HWA paramsets reserved for the Doppler DPU. The number of HWA paramsets required by this DPU is a function of the number of TX antennas used in the configuration: numParamSets = 2 x (Number of TX antennas) + 2 The DPU will use numParamSets consecutively, starting from paramSetStartIdx. . More...

uint32_t	paramSetStartIdx
	HWA paramset Start index. Application has to ensure that paramSetStartIdx is such that [paramSetStartIdx, paramSetStartIdx + 1, ... (paramSetStartIdx + numParamSets - 1)] is a valid set of HWA paramsets. . More...

uint32_t	hwaMemInpAddr
	HWA input memory bank address. More...

uint32_t	hwaMemOutAddr
	HWA output memory bank address. More...

DPU_Aoa2dProc_HWA_Option_Cfg	aoa2dRngGateCfg
	HWA Doppler FFT Parmas set configuration (performing Doppler FFT and antenna mapping) More...

uint8_t	dmaTrigSrcChan
	HWA param set dma trigger source channel. More...

uint8_t DPU_Aoa2dProc_HwaCfg::firstStageScaling

Indicates if HWA should enable butterfly scaling (divide by 2) of the first radix-2 stage. Depending on the window definition, user may want to skip the first stage scaling in order to avoid signal degradation.
Options are:
Disable first stage scaling: firstStageScaling = DPU_AOA2DPROC_FIRST_SCALING_DISABLED
Enable first stage scaling: firstStageScaling = DPU_AOA2DPROC_FIRST_SCALING_ENABLED
Note: All other butterfly stages have the scaling enabled. This option applies only for the first stage.

◆ numParamSets

uint8_t DPU_Aoa2dProc_HwaCfg::numParamSets

Number of HWA paramsets reserved for the Doppler DPU. The number of HWA paramsets required by this DPU is a function of the number of TX antennas used in the configuration:
numParamSets = 2 x (Number of TX antennas) + 2
The DPU will use numParamSets consecutively, starting from paramSetStartIdx.
.

◆ paramSetStartIdx

uint32_t DPU_Aoa2dProc_HwaCfg::paramSetStartIdx

HWA paramset Start index.
Application has to ensure that paramSetStartIdx is such that
[paramSetStartIdx, paramSetStartIdx + 1, ... (paramSetStartIdx + numParamSets - 1)]
is a valid set of HWA paramsets.
