Adi Evaluation board CN0284 beamforming processing need algorithm?

The circuit shown in CN0284 is performing the beamforming processing, but is doing this with analog circuits, rather than on a DSP. The video that you've linked to above is doing similar processing, but that is being done on a SigmaDSP. The analog beamforming in CN0284 is done with allpass filters (delay) and summing amplifiers (subtraction). With the two microphone boards connected to the power & processing board, this design is set up to do microphone array beamforming.
