In this Paper 1, we present an asynchronous array design for the minimum variance distortionless response MVDR beamformers. The array transforms the constrained problem into unconstrained form, enabling an unconstrained processor to compute the beamformer output. The key component of the array is a communication protocol which controls input data flow properly and efficiently. In the design, instead of using global control, self-timed processing elements PEs and communication protocols are provided. The asynchronous array for MVDR beamformers can significantly speed up the total computation time. Finally, we present an algorithm in Occam2 languages for the asynchronization scheme of the processes. It is felt that the array has promise for real-time beamforming with planar array antennas.
