An Accumulator Chip

A large-scale integrated-circuit chip has been designed under the sponsorship of the Air Force Avionics Laboratory. The chip was developed as part of a logic synthesizer effort of the Design Automation group at Litton Systems, Inc., Guidance and Control Systems Division. It was designed as a type or category to be multiply used with one other gating type chip whose format is prescribed by the logic synthesizer. A major goal of this effort will be to design a complete digital system by design-automated techniques using only these two types of chips in a large-scale array. This paper provides a logical description of the chip followed by an illustrative example of its employment in a small array.
