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...

Field Documentation

winSym

uint8_t DPU_AoAProcHWA_HwaCfg::winSym

Indicates if HWA window is symmetric or non-symmetric. Use HWA macro definitions for symmetric/non-symmetric.

windowSize

uint32_t DPU_AoAProcHWA_HwaCfg::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

window

int32_t* DPU_AoAProcHWA_HwaCfg::window

Pointer to Doppler FFT window coefficients.

winRamOffset

uint32_t DPU_AoAProcHWA_HwaCfg::winRamOffset

HWA window RAM offset in number of samples.

vectorRamSize

uint32_t DPU_AoAProcHWA_HwaCfg::vectorRamSize

Vector Multiplication RAM size in bytes. This is the number of coefficients to be programmed in the HWA for the Vector Multiplication functionality.

vectorRam

cmplx32ImRe_t* DPU_AoAProcHWA_HwaCfg::vectorRam

Pointer to Vector Multiplication RAM coefficients.

vecRamOffset

uint32_t DPU_AoAProcHWA_HwaCfg::vecRamOffset

HWA vector multiplication RAM offset in number of samples.

paramSetStartIdx

uint32_t DPU_AoAProcHWA_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.
