Abstract
-This brief introduces a novel (or ancient) technique for highspeed arithmetic. The new proposed method is based on the still-used Chinese abacus. We show that proper electronic circuits, based on pass transistor and domino logic, allow us to achieve the same functions of the Chinese abacus. Simulations with a 0.35-μm CMOS technology show that either a pipeline 8-bit adder and 8×8 multiplier can run at a speed as high as 1 GHz
