    This tutorial places the developments and potential of multiple-valued signals and logic in the relevant context of binary and two-valued signals. It covers: the role of multivalued logic (MVL) in the binary world; multivalued representation; binary-related radices; multivalued functions; storage techniques in MVL; and implementation issues. An overview of applications is included.<> View full abstract»

    The authors compare the performance of two-valued and m-valued ICs for MOS and bipolar technologies according to speed, chip area, and power dissipation. They present the basic concepts and the basic types of m-valued circuits that make a serious comparison possible. They cover Post algebra and m-valued circuitry, m-valued current-mode circuits, and m-valued memory cells.<> View full abstract»

    A description is given of a 32*32-bit signed digit multiplier implemented with multiple-valued, bidirectional, current-mode circuits and based on two-microcomputer complementary metal-oxide-semiconductor technology. The multiplier can perform 32-bit two's-complement multiplication with three-stage SD full adders using a binary-tree addition scheme The effective multiplier size in the chip and the ...

    Shows a method of designing programmable logic arrays (PLAs) using multiple-valued input, two-valued output functions (MVITVOFs). A MVITVOF is an extension of the two-valued logic function. An expression for a MVITVOF directly represents a multiple-output PLA with decoders. Each product of the expression corresponds to each column of the PLA, so the number of products; in the expression equals the... View full abstract»
