2-d convolution engine.

Hi

A digital IC to perform simple convolution of 2D images. Convolution applies a moving window of a set size (3x3 and upwards) to each pixel in an image. The kernel contains coefficients of weighting factors. As the kernel is moved over an image each coefficient is multiplied by the corresponding pixel value in the image and the products are added. Each sum is placed in the central pixel in a new image. (See figure on Overview page). Convolution is typically used in image processing as a spatial filter for tasks such as blurring (low pass), sharpening (high pass), or edge enhancement.
The final IC contains one SRAM, two separate datapaths, and synthesized control logic. It measures approximately 2400 lambda by 2100 lambda, including routing for power and ground. It will be manufactured with the MOSIS 1.2u, 2 metal, 1 poly process (lambda=0.6um) on a 2.2mm by 2.2mm die and placed in the tinyCHIP 40 pin DIP package.
