Detailed Description

dopplerProc DPU HWA configuration parameters

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

Data Fields
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_UDOPPROC_FIRST_SCALING_DISABLED Enable first stage scaling: firstStageScaling = DPU_UDOPPROC_FIRST_SCALING_ENABLED Note: All other butterfly stages have the scaling enabled. This option applies only for the first stage. . More...

uint32_t	paramSetStartIdx
	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. .

◆ firstStageScaling

uint8_t DPU_uDopProc_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_UDOPPROC_FIRST_SCALING_DISABLED
Enable first stage scaling: firstStageScaling = DPU_UDOPPROC_FIRST_SCALING_ENABLED
Note: All other butterfly stages have the scaling enabled. This option applies only for the first stage.
.

◆ paramSetStartIdx

uint32_t DPU_uDopProc_HwaCfg::paramSetStartIdx

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.
.

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.

◆ hwaParamsSaveLoc

DPU_uDopProc_HwaParamSaveLoc DPU_uDopProc_HwaCfg::hwaParamsSaveLoc

HWA Params save location.

◆ dmaTrigSrcChan

uint8_t DPU_uDopProc_HwaCfg::dmaTrigSrcChan
