Abstract :
An architecture and a design for a high-speed CMOS digital convolver which can be used for real-time one-dimensional (1-D) and two-dimensional (2-D) signal processing are presented. In the 2-D mode this device can be used to convolve 10-bit image data with a 3×3 or 2×5 2-D eight-bit-per-coefficient impulse response at 20 M samples/s throughput. In 1-D applications it can be used as a ten-tap finite-impulse response (FIR) filter. Devices can be cascaded to increase the order of the convolution reference in both dimensions
