TDA3XEVM: Getting the Noise Floor Parameter Out of PkDetect Alg

This would be inside the EVE algorithm files. I will loop in the EVE expert to help you.

Thanks and Regards,

Hi Khai,

    The noise floor is calculated inside vcop_peak_detection_CFARCA_thresholding function which is located inside kernels\radarlib\vcop_peak_detection\src_kernelC\vcop_peak_detection_kernel.k. To expose this outside the kernel you will need to allocate a new buffer inside VCOP's memory along with the corresponding DMA ping pong to write it back to external memory.

Hi Anshu,

I found the code. I am not familiar with EVE kernel code at all. Can you be more precise on steps taken to wire this parameter out?

Thanks,

Hi Khai,

    The changes will need you to understand a bit of EVE and BAM framework. Can you compute the noise floor  only for the detected peaks as post processing ( this could be done in DSP if you have some MHz available there)?

Hi Khai,

    Are you able to make progress on this issue?

Not really. It's a low priority task for us right now but can resurface.

I have a question. How is the PkDetect outBuf->energyBuf calculated? what is its unit?

Thanks,
