HWA主要通过硬件做radar FMCW算法方面的处理，分担DSP的一些算法，可以和DSP同时运行。两者可以传递数据。请看下面的HWA文档说明。 Alternately, if the ADC output samples are required to be pre-processed by the DSP before processing by the Hardware Accelerator, then the ADC buffer sharing can be disabled (see the FFT1DEN register bit), such that the DSP can access the ADC buffer, perform the pre-processing as needed, and then write to the dedicated local memories (ACCEL_MEM0 and ACCEL_MEM1) of the Radar Hardware Accelerator for further processing using the accelerator. https://www.ti.com/lit/ug/swru526b/swru526b.pdf
