Programme logic cell and array

Abstract From the Canadian patent

An improved programmable logic cell (1) for use in a programmable logic array comprising cells which are arranged in two-dimensional matrix of rows and columns and are interconnected by a twodimensional array of direct connections between a cell (1) and its four nearest neighbors one to its left, (or to the West) (3a, 3b 7a, 7b) and one to its right, (or to the East) (5a 5b, 9a, 9b), one above it (or to, the North) (2a 2b, 6a, 6b) and one below it (or to, the South) (4a 4b, 8a, 8b). Each cell receives input, (s) from each of its nearest neighbors and additional inputs) from a bus, pin, or neighbor and may be programmed to generate a variety of logical functions at its outputs which connect …
