Cellular-array negabinary multiplier
L.S. Houselander · Electronics Letters · 1974
It is shown that a particular cellular-array multiplication technique used in integrated-circuit multipliers is equivalent to the chequerboard method of John Napier, the 16th-Century mathematician. Further, a cellular-array multiplier based upon the use of ‘negabinary’ numbers is developed. This is a 4-quadrant multiplier, after the style of Napier's chequerboard, that requires no separate circuitry for sign manipulation.
