G06F 7/501

Half or full adders, i.e. basic adder cells for one denomination

Introduced: January 2006

Full Title

Full titles differ between systems:

IPC:

Methods or arrangements for processing data by operating upon the order or content of the data handled > Methods or arrangements for performing computations using exclusively denominational number representation, e.g. using binary, ternary, decimal representation > using non-contact-making devices, e.g. tube, solid state device; using unspecified devices > Adding; Subtracting > Half or full adders, i.e. basic adder cells for one denomination

CPC:

Methods or arrangements for processing data by operating upon the order or content of the data handled (logic circuits H03K19/00) > Methods or arrangements for performing computations using exclusively denominational number representation, e.g. using binary, ternary, decimal representation > using non-contact-making devices, e.g. tube, solid state device; using unspecified devices > Adding; Subtracting (G06F7/483 - G06F7/491, G06F7/544 - G06F7/556 take precedence) > Half or full adders, i.e. basic adder cells for one denomination

Of 4 combined children, 2 exist in both systems.
