ABSTRACT:
A multiplier generates an array of partial products. The partial products are reduced in a converter having cells defining rows and columns. Cells adjacent to adders alternate between a cell that provides non-inverted outputs and a cell that provides inverted outputs, such that alternate rows of cells operate on non-inverted data and the intervening rows of cells operate on inverted data. A multiplexer for receiving the outputs from a row of cells may be an inverting multiplexer or a non-inverting multiplexer depending on the cell arrangement.
