Arithmetic Unit of a Computing Element in a Global, Highly Parallel Computer

Abstract: The arithmetic unit of a digital computing element for a proposed globally controlled, highly parallel computer having up to thousands of such computing elements is described. Because operand words are regarded as circular, and any digit position may be designated as most significant during an operation, the atom of the computing element is the digit position logic, i.e., the computing elements are themselves composed of identical modules for each digit. The entire computing element, consisting of the arithmetic unit, an 8192 bit IGFET memory, and a special purpose input unit can be packaged on a 3.75 inch by 4.5-inch ceramic substrate using beam lead integrated circuits.

Some applications of cellular logic arithmetic arrays

Abstract: The paper describes two types of full multiplier. These are combinational logic networks based on a cellular structure. Some applications of these multipliers are outlined, including approximation methods for obtaining the reciprocal of a binary number, and for the quotient of two binary numbers.
