IWR6843: About Allocation of each DPU

Part Number: IWR6843

Tool/software:

Hi,

I am currently developing using IWR6843.

In the IWR6843 sample code, I think each DPU is processed by HWA or DSP.

In the sample code, the assignment is as follows:

HWA Processing : Range Proc DPU

DSP Processing : Static Clutter Removal, Doppler Proc DPU, CFAR DPU, AoA DPU

My Question : 

What are the decision criteria for which resource to use for which DPU?

Why is only Range Proc DPU processed by HWA?

Best Regards, Thanks

  • Hello, 

    For the 6843 device which has access to both HWA and DSP it is at the discretion of the developer as to which resource should be used for each processing block. In the specific sample you highlighted range processing is done on the HWA and everything else on the DSP however on other examples it might be done differently. For example, the 6843AOP out of box example, 6843AOP has access to all the same processing elements however in that example all of the processing for each of the dpus is done on the HWA.
