IWR6843AOPEVM: How to use C674X DSP core on the IWR6843AOPEVM

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: MMWAVE-SDK, IWR6843AOP

Hi all,

I am trying to test my radar processing algorithm using an IWR6843AOPEVM and its Out-of-box demo (xwr64xx) in the MMWAVE-SDK 03_02_00_06_AOP, and it seems that it uses only R4F and the hardware accelerator.

I want to use a C674X DSP core on the IWR6843AOP for implementing own signal processing algorithms to use on my algorithm.

I wonder if there are any software samples or demos for using both R4F and DSP of IWR6843AOP, and if not, if there are any plans to support that.

Regards,

Woonggy Kim.

    Hi Woonggy,

    See this list of the labs compatible with the IWR6843AoPEVM. I believe only the Robotics and Out of Box labs use the 64xx base, and the others utilize the C674x.

    There are also regular updates to the Industrial Toolbox so check back often!

    Regards,

    Dear Akash,

    Thanks for your prompt reply.

    On the link you suggested, I have considered 3 Labs -- vital signs, high accuracy range measurement, gesture recognition -- and have confirmed that these labs support IWR6843AOP with C674x DSP.

    One more thing to consider is that my signal processing algorithm uses 3 Tx antennas to scan both elevation and azimuth angle, but the labs above only use 2 Tx antennas.

    I modified the labs to use 3 Tx antennas, but a BSS event (CPU fault) is triggered and the system downs and could not use it.

    Are there any solutions to use 3 Tx antennas on the IWR6843AOP with C674x DSP?

    Regards,
