Abstract

A circuit is provided for addition of multiple binary numbers. The circuit includes a 4-to-2-compressor configured for calculating a compressed representation from four binary numbers received via operand inputs of the 4-to-2-compressor. The 4-to-2-compressor includes a first sub-circuit and a second sub-circuit. Each of the first sub-circuit and the second sub-circuit is configured for transmitting a bitwise inverted representation, of a compressed representation, from three binary numbers.
