Reduction in the number of PAL macrocells in the circuit of a Moore FSM

Alexander Barkalov, Larysa Titarenko, Sławomir Chmielewski (2007)

International Journal of Applied Mathematics and Computer Science

Similarity:

Optimization methods of logic circuits for Moore finite-state machines are proposed. These methods are based on the existence of pseudoequivalent states of a Moore finite-state machine, a wide fan-in of PAL macrocells and free resources of embedded memory blocks. The methods are oriented to hypothetical VLSI microcircuits based on the CPLD technology and containing PAL macrocells and embedded memory blocks. The conditions of effective application of each proposed method are shown. An...

Design of mealy finite-state machines with the transformation of object codes

Alexander Barkalov, Alexander Barkalov (2005)

International Journal of Applied Mathematics and Computer Science

Similarity:

An optimization method of the logic circuit of a Mealy finite-state machine is proposed. It is based on the transformation of object codes. The objects of the Mealy FSM are internal states and sets of microoperations. The main idea is to express the states as some functions of sets of microoperations (internal states) and tags. The application of this method is connected with the use of a special code converter in the logic circuit of an FSM. An example of application is given. The effectiveness...

Design of microprogrammed controllers to be implemented in FPGAs

Remigiusz Wiśniewski, Alexander Barkalov, Larisa Titarenko, Wolfgang A. Halang (2011)

International Journal of Applied Mathematics and Computer Science

Similarity:

In the article we propose a new design method for microprogrammed controllers. The traditional structure is improved by modifying internal modules and connections. Such a solution allows reducing the total number of logic elements needed for implementation in programmable structures, especially Field Programmable Gate Arrays (FPGAs). Detailed results of experiments show that on the average the application of the proposed methods yields up to 30% savings as far as the destination device...

On the structure of linear recurrent error-control codes

Michel Fliess (2002)

ESAIM: Control, Optimisation and Calculus of Variations

Similarity:

We are extending to linear recurrent codes, i.e., to time-varying convolutional codes, most of the classic structural properties of fixed convolutional codes. We are also proposing a new connection between fixed convolutional codes and linear block codes. These results are obtained thanks to a module-theoretic framework which has been previously developed for linear control.

Application of triple correlation and bispectrum for interference immunity improvement in telecommunications systems

Pavel Molchanov, Alexandr Totsky (2008)

International Journal of Applied Mathematics and Computer Science

Similarity:

This paper presents a new noise immunity encoding/decoding technique by using the features of triple correlation and bispectrum widely employed in digital signal processing systems operating in noise environments. The triple correlationand bispectrum-based encoding/decoding algorithm is tested for a digital radio telecommunications binary frequency shift keying system. The errorless decoding probability was analyzed by means of computer simulation for the transmission and reception of...

Multi-label classification using error correcting output codes

Tomasz Kajdanowicz, Przemysław Kazienko (2012)

International Journal of Applied Mathematics and Computer Science

Similarity:

A framework for multi-label classification extended by Error Correcting Output Codes (ECOCs) is introduced and empirically examined in the article. The solution assumes the base multi-label classifiers to be a noisy channel and applies ECOCs in order to recover the classification errors made by individual classifiers. The framework was examined through exhaustive studies over combinations of three distinct classification algorithms and four ECOC methods employed in the multi-label classification...
