ABSTRACT:
A convolver including a matrix of multipliers for providing a plurality of products PiCj of input data Pi and a dedicated coefficient Cj and each connected to a data input by a buffer which stores and delays input data Pi as a function of its position in the matrix and the length of the row M of the input data array. The buffers include row buffers which are programmable for various input data array row lengths M as well as programmable input buffer stages. A second data input is selectively connected to the multipliers or to an output adder for connection to external delay units or cascade connection to other convolvers. Unique control logic is provided to change the structure of the convolver as well as reset and program various elements using common inputs.
