AWRL1432: What role is the function DPU_RangeProcHWA_control

Rata Zhang

Part Number: AWRL1432

Tool/software:

Hi,

In the AWRL1432 demo,there is a function DPU_RangeProcHWA_control, What role is it?

/* Give initial trigger for the next frame */
retVal = DPU_RangeProcHWA_control(gMmwMssMCB.rangeProcDpuHandle, DPU_RangeProcHWA_Cmd_triggerProc, NULL, 0);

My first understanding is that it will invoke Tx antenna to transimit mmwave and at the same time transfer ADC data, is that right?

My second understanding is that this function only transfer ADC data and can't invoke Tx antenna to transimit mm wave, the time for transimit mm wave is decided by frame period, for example if the frame period is 100ms, then mm wave is transimitted every 100ms,not controlled by this function, is that right?

Thanks!

BR,

Rata

Hi,

The range processing is performed in our dedicated hardware accelerator (HWA) and this function is part of the control. If you take a look at the the demo documentation, there is more description and diagrams that may help better explain. I've listed where to find these in the SDK install.
