dopplerProc DPU HWA configuration parameters
The structure is used to hold the HWA configuration parameters for the Doppler Processing DPU
Data Fields | |
| uint8_t | winSym |
| Indicates if HWA window is symmetric or non-symmetric. Use HWA macro definitions for symmetric/non-symmetric. More... | |
| uint32_t | windowSize |
| Doppler FFT window size in bytes. This is the number of coefficients to be programmed in the HWA for the windowing functionality. The size is a function of numDopplerChirps as follows: If non-symmetric window is selected: windowSize = numDopplerChirps * sizeof(int32_t) If symmetric window is selected and numDopplerChirps is even: windowSize = numDopplerChirps * sizeof(int32_t) / 2 If symmetric window is selected and numDopplerChirps is odd: windowSize = (numDopplerChirps + 1) * sizeof(int32_t) / 2 More... | |
| int32_t * | window |
| Pointer to Doppler FFT window coefficients. More... | |
| uint32_t | winRamOffset |
| HWA window RAM offset in number of samples. More... | |
| 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_DOAPROC_FIRST_SCALING_DISABLED Enable first stage scaling: firstStageScaling = DPU_DOAPROC_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... | |
| DPU_DoaProc_HWA_Option_Cfg | doaRngGateCfg |
| 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_DoaProc_HwaCfg::winSym |
