Modular input-programmable logic circuits for use in a modular array

Abstract

A general circuit design for the various functional types of modules used in the Elemental Processors of a Modular Array Processor. These modules nominally include an input-programmable logic circuit and closely associated memory register. They also include a common means of transferring data to and from a data bus for communicating data to the other modules present within their respective Elemental Processors. The various functional types of modules are realized through the use of logic circuits of different specific designs. Each particular type of logic circuit is designed to implement all of the related logical and data manipulative operations necessary to provide a general data processing function, such as those of accumulator, memory, counter, and comparator. This allows the logic circuit to receive data from the data bus, perform a selected data manipulation operation consistent with the module's functional type on the data received in combination with data stored in the memory register and to store the resultant data in the memory register, and to transmit the stored resultant data back to the data bus.
