This paper presents a design method for three-level programmable logic arrays (PLAs), which have input decoders and two-input EXOR gates at the outputs. The PLA realizes an EXOR of two sum-ofproducts expressions (EX-SOP) for multiple-valued input two-valued output functions. We developed an output phase optimization method for EXSOPs where some outputs of the function are minimized in the compl...

Decision diagrams are the state-of-the-art representation for logic functions, both binary and multiple-valued. Here we consider issues regarding the efficient implementation of a package for the creation and manipulation of multiple-valued decision diagrams (MDDs). In particular, we identify issues that differ from binary decision diagram packages. We describe a matrix method for level interch...

This paper presents a Field-Programmable Digital Filter (FPDF) IC that employs carry-propagation-free redundant arithmetic algorithms for faster computation and multiplevalued current-mode circuit technology for high-density lowpower implementation. The original contribution of this paper is to evaluate, through actual chip fabrication, the potential impact of multiple-valued current-mode circu...

The paper investigates the characterisation of vague concepts within the framework of modal logic. This work builds on the su-pervaluation approach of Fine and exploits the idea of a precisiication space. A simple language is presented with two modalities: a necessity operator and an operatorìt is unequivocal that' which is used to articulate the logic of vagueness. Both these operators obey th...

This paper presents a fine-grain bit-serial reconfigurable VLSI architecture using multiple-valued switch blocks and binary logic modules. Multiple-valued signaling is utilized to implement a compact switch block. A binary-controlled current-steering technique is introduced, utilizing a programmable three-level differential-pair circuit to implement a high-performance low-power arbitrary two-va...

Multiple sequence alignment is the most fundamental and essential task of computational biology, and forms the base for other tasks of bioinformatics. In this paper, two different approaches to sequence alignment have been discussed and compared. The first method employs Boolean algebra which is a two-valued logic whereas the second is based on Fuzzy logic which is a multi-valued logic. Both th...

Multi-value logic is defined as a non-binary logic and involves the switching between more than two states. The design of Multiple Valued Logic (MVL) digital circuits is performed by increasing the representation domain from the two level (N=2) switching algebra to N > 2 levels. More data can be transmitted by single wire having more than two levels. Multiple-valued logic (MVL) application in t...
