Introduction

Implements range processing functionality using HWA. Range FFT processing is done by HWA hardware. Based on the RF parameters, rangeProcHWA configures hardware accelerator FFT engine accordingly. It also configures data input and output EDMA channels to bring data in and out of range Processing memory.

HWA FFT process is triggered by hardware based trigger -"chirp data available" which is hooked up to HWA internally in hardware.

After FFT processing is done, HWA generates interrupt to rangeProcHWA DPU, at the same time triggers EDMA data output channel to copy FFT results to radarCube in configured format. EDMA interrupt done interrupt is triggered by EDMA hardware after the copy is completed.
