Programmable Cellular arrays†
B. S. RAJU, S.K. Mullick · International Journal of Control · 1971
Different cellular cascades and arrays for realizing arbitrary logical functions as well as special-purpose arrays for parallel arithmetical operations are reviewed. A 4 X 3 cellular array is designed using a basic cell which realizes all the Boolean functions of its two input variables and also includes a flip-flop. The individual cells in the array can be selected and programmed from outside the package for different logic functions. The necessary peripheral logic for accomplishing this is suggested. A large variety of logical subsystems like full adders, code converters, shift registers, etc. are synthesized using these cellular arrays.
