Abstract :
A programmable convolution array (PCA) architecture is described. The architecture uses CMOS light sensors, each connected to an amplifier. The aggregate of amplifiers yields a sum of products and computes convolution of the image with kernels of arbitrary size. A chip based on this architecture and test results are presented
