Recent studies concerning Spiking Neural Networks show that they are a powerful tool for multiple applications as pattern recognition, image tracking, and detection tasks. The basic functional properties of SNN reside in the use of spike information encoding as the neurons are specifically designed and trained using spike trains. We present a novel and efficient frequency encoding algorithm with Gabor-like...
Six indium phosphide integrated circuits power the front end of Agilent's new Infiniium 90000 X-Series Oscilloscope and InfiniiMax III Probing System. Setting a new standard in real-time oscilloscope performance, the chipset delivers 32 GHz of true analog bandwidth directly in hardware and is ideally suited to characterize and debug the high-speed signals of emerging serial data standards, fully capturing...
The paper presents a formal design methodology for reconfigurable, modular digital controller logic synthesis. The project of embedded controller starts from behavioral, graphical hierarchical and concurrent state machine description in Unified Modeling Language (UML). After the hierarchical encoding of nested and concurrent superstates, the UML state machine diagram can be directly and automatically...
In the paper we propose a new method of the microinstruction length reduction in the designing process of microprogrammed controllers. The algorithm is based on the representation of the compatibility classes with hypergraphs. The whole process of the microinstruction length reduction is presented in details and illustrated by an example. Finally, proposed idea is compared with traditional solutions,...
In this paper useful methods of concurrent processes synchronization in UML state machine diagrams are presented. It is not easy to transform complex behaviour description into statecharts, even if the formal specification has already been given, for example as a hierarchical Petri net. Both graphical forms of specifications can be used simultaneously, especially when overlapped concurrent processes...
This work presents experimental results on online recognition of handwritten signature. The system makes use of dynamic data such as trajectory, pen velocity, pen pressure, pen azimuth, and pen altitude collected at the time of signing. In order to evaluate the effectiveness of the system several experiments are carried out. Online signature database from signature verification competition (SVC) 2004...
The paper presents a design methodology for reconfigurable, modular digital controller synthesis. It starts with behavioral specifications and goes through Register Transfer Level to rule-based logic expressions, rewritten in hardware description languages. The logic controller program can be initially specified as Petri net, IEC1131 Sequential Function Chart or UML state machine diagram. All considered...
The method of hardware amount optimization in the circuit of addressing of compositional microprogram control unit is proposed. Method is based on the formation of the number of input by finite-state-machine of addressing and its transformation in the address of operational linear chain. Proposed structure of control units is oriented on application in the telecommunication systems.
In the paper the outline of the modular, reconfigurable logic controller design is presented. As the initial specification, sequential function chart (SFC-1131) is considered, as well as its equivalent textual specification in structured text. The focused items of design are: modification of the initial specification of the controller by means of introducing separate control part, described as SFC...
