G06F 7/506

with simultaneous carry generation for, or propagation over, two or more stages

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 > in bit-parallel fashion, i.e. having a different digit-handling circuit for each denomination > with simultaneous carry generation for, or propagation over, two or more stages

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) > in bit-parallel fashion, i.e. having a different digit-handling circuit for each denomination > with simultaneous carry generation for, or propagation over, two or more stages

IPC and CPC are identically structured here. All 2 subcodes exist in both systems.

IPC defines codes here since 2006.
