Advancing from two to four valued logic circuits

Abstract

To further increase the speed of computation, this paper proposed to increase from binary to four-valued logic circuits. Four-valued logic circuits allow each wire to carry two bits at a time, each logic gate to operate two bits at a time, and each memory cell to record two bits at a time. The speed of communication between devices is also increased due to the increase in bandwidth of each wire. To make the base-four computations possible, this paper described the design and implementation of four-valued logic gates, memory cells, and flip-flops. To allow for future developments, the design of the memory cell and the flip-flop provided in this paper can be extended to be used for infinite-valued or Fuzzy logic circuits, for fully exploiting many-valued logics and fuzzy paradigms in hardware.
