1. A method for computing filter coefficients of a beamformer based on a segment of input samples comprising the steps of:

  • dividing the segment of input samples into a plurality of blocks of input samples;

    receiving the plurality of blocks of input samples in a shared memory at a first rate wherein a first block of the plurality of blocks is received in a shared memory at a first time;

    reading the plurality of blocks of input samples from the shared memory at a second rate wherein the first block of the plurality of blocks is read from the shared memory at a second time, computing a plurality of partial covariance matrices for the plurality of blocks read from the shared memory;

    adding the plurality of partial covariance matrices.
