A digital processor performs an N-point convolution or correlation of q-bit coefficients with data words guard band extended to p bits. The processor includes an array of one-bit clock-activated gated full adder cells arranged in N rows and q columns. Each cell is arranged to input data, carry and cumulative...http://www.google.de/patents/US4885715?utm_source=gb-gplus-sharePatent US4885715 - Digital processor for convolution and correlation
