Abstract:
1. A reconfigurable filter node comprising: an input data memory adapted to store a plurality of input data values; a filter coefficient memory adapted to store a plurality of sets of filter coefficient values, each set having a plurality of filter coefficient values; and a plurality of computational units adapted to simultaneously compute a set of filter data values from the input data values and one of the sets of filter coefficients; wherein the reconfigurable filter node is adapted to successively compute a plurality of sets of filter data values, each set of filter data values computed by a computational unit that performs a filter convolution on a portion of the input data values using a different one of the plurality of sets of filter coefficients; and each computational unit being adapted to receive a different one of the sets of filter coefficients in the plurality of filter coefficients so that different ones of the computational units apply different functions to the portion of the input data values.
