INPUT STRUCTURE FOR PARALLEL ADDER IN POSITION-SIGN CODES f(+/-)(VERSIONS) Russian patent published in 2010 - IPC G06F7/50 

Abstract RU 2378682 C2

FIELD: physics; computer engineering.

SUBSTANCE: invention relates to computer engineering and can be used in designing arithmetic devices for carrying out arithmetic operations of summation and subtraction in position-sign codes. Each bit of the adder is made in form of structure-equivalent channels - positive and conditionally negative. In one version of implementation, the ith bit of each channel contains two OR logic components, two NAND logic components, two inverter gates and an AND logic component.

EFFECT: simplification of functional structure of the adder and faster operation.
