Introduction

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

The process is triggered by the peak location availability based on 1D FFT.

After HWA processing is done, it generates interrupt to zoomProc DPU, at the same time triggers EDMA data output channel to copy zoom FFT results. EDMA interrupt done interrupt is triggered by EDMA hardware after the copy is completed.
