A Non-binary Parallel Arithmetic Architecture

In this paper we present a novel parallel arithmetic architecture using an efficient non-binary logic scheme. We show that by using parallel broadcasting (or domino propagating) state signals, on short reconfigurable buses equipped with a type of switches, called GP (generate-propagate) shift switches, several arithmetic operations can be carried out efficiently. We extend a recently proposed shift switching mechanism by letting the switch array automatically generate a semaphore to indicate the end of each domino process. This reduces the complexity of the architecture and improves the performance significantly.
