Could SHARC be a driver for 256 PDM microphones like ADMP521?

Hi,

 

I've started a discussion in Beamforming with MEMS microphones. And now I want to use 256 microphones ADMP521 and 128

ADAU7002 (a new IC that can do PDM-to-I2S/TDM decimation) for beamforming application. So I will have 32 TDM8 lines. What kind and how much of SHARCs or another DSPs I need for this app? Could you recommend me a solution for this high density data path? I just want to estimate a recourses needed for process signals from 256 mics. Could anyone help me?

 

Regards,

John.
