AWRL1432: HWA DC subtraction

KT Lin

Part Number: AWRL1432

Tool/software:

I'm new to TI's mmwave radar and want to perform DC subtraction, but I don't know how to integrate the demo code (MMWAVE_L_SDK_05_05_03_00\examples\drivers\hwa\hwa_dc_sub) into the actual processing chain in C:\ti\MMWAVE_L_SDK_05_05_03_00\examples\mmw_demo\mmwave_demo.

Could TI provide reference code? Thank you!

Hello.

We do not have any reference software for this. However, if you want to perform this operation in sequence with the rest of the processing chain, you can break it up similar to the DPUs provided in the SDK(init, config, process). The init and config set up the paramsets for the operation, and the process function triggers the HWA accelerator and performs the operation. I would look at any of the DPU source code for reference on how to set this up and how it is called in the processing chain.

Sincerely,

Santosh

Hi Santosh,

Thank you for your reply!

I'm not sure at which point in the processing chain(mmWave demo) I should insert the DC subtraction DPU? I'm guessing it's only for updating the radar cube data, correct?
