As integration levels in FPGA devices have increased over the past decade, the structure of programmable logic resources has become more diversified. Recently, Altera Corporation has introduced a new family of LUT-based FPGAs that have been augmented with userconfigurable programmable logic array blocks (PLAs). In this paper a novel FPGA technology mapping approach is described that automatical...

Many System-on-a-Chip devices would benefit from the inclusion of reprogrammable logic on the silicon die, as it can add general computing ability, provide run -time reconfigurability, or even be used for post -fabrication modifications. Also, by catering the logic to the SoC domain, additional area/delay/power gains can be achieved over current, more general reconfigurable fabrics. This paper ...

In this paper, we present the condition for the effective wire addition in Look-Up-Table-based (LUT-based) field programmable gate array (FPGA) circuits, and an optimization procedure utilizing the effective wire addition. Each wire has different characteristics, such as delay and power dissipation. Therefore, the replacement of one critical wire for the circuit performance with many non-critic...

F ield programmable gate array (FPGA) components are widely used nowdays to implement various algorithms, such as digital filtering, in real time. The emergence of dynamically reconfigurable FPGAs made it possible to reduce the number of necessary resources to carry out an image-processing task (tasks chain). In this article, an image-processing application, image rotation, that exploits the FP...

In recent years, reversible logic has emerged as a promising computing paradigm having application in low power CMOS, quantum computing, nanotechnology, and optical computing. The classical set of gates such as AND, OR, and EXOR are not reversible. In this paper, the authors have proposed reversible programmable logic array (RPLA) architecture using reversible Fredkin and Feynman gates. The pro...

As in binary, a multiple-valued programmable logic array (PLA) realises a sum-ofproducts expression specified by the user. However, in multiple-valued logic, there are many more operations than in binary, and an important question is the choice of operations which provides the greatest number of functions for a given chip area. In this paper, we analyse various PLA configurations using operatio...

Following the simple Programmable Logic Device (SPLD) and Field Programmable Gate Array (FPGA) generations a third generation of programmable logic technologies is now reaching the marketplace. These new architectures are driven by the move to system level integration and fast expanding markets such as networking and wireless communications which are not addressed adequately by mainstream FPGA'...

Firstly, this paper presents fuzzy logic based approaches for building a tool for measuring ereadiness of a country. This paper proposes fuzzy logic for realizing the measuring tool as fuzzy logic allows processing of heterogeneous indicators and imprecise values assigned for them. The tool is constructed by using one or more fuzzy logic based inference engines. Secondly, due to the problems in...

Picat is a logic-based multi-paradigm dynamic language that integrates logic programming, functional programming, constraint programming, and scripting. The Picat language is underpinned by the core logic programming concepts, including logic variables, unification, and nondeterminism. Picat takes many constructs from other languages, among which functions, list and array comprehensions, loops,...
