Multi-Valued Logic Circuit Design and Implementation

To further increase the speed of computation, this paper aims to design and implement digital circuits entirely within the domain of multi-valued logic. In a fourvalued logic circuit, each wire carries two bits at a time, each logic gate operates two bits at once, and each memory cell records two bits at one time. To make the multi-valued computation possible, this paper describes a simple fourstep process for designing multi-valued circuits to implement any multi-valued functions. The design of a fourvalued adder is provided as an example. This paper also contributes new designs for multi-valued memory and flipflops, which can be extended to be used for infinite-valued or Fuzzy logic circuits, for fully exploiting many-valued logic and fuzzy paradigm in hardware. The multi-valued circuit design methodology and the multi-valued memory provide the necessary and sufficient tools and components for designing multi-valued systems entirely within the domain of multi-valued logic. 
