Vision-based sensing algorithms are computationally-demanding tasks due to the large amount of data acquired and processed. Visual sensors deliver much information, even if data are redundant, and do not give any additional information. A Selective Change Driven (SCD) sensing system is based on a sensor that delivers, ordered by the magnitude of its change, only those pixels that have changed m...

In this work we are describing hardware implementation of Kohonen SelfOrganizing Map. We examined existing neurocomputers and decided to work out our own neurocomputer with a different, more suitable architecture. Our neurocomputer is being realized on FPGA (Field-Programmable Gate Array). In this article we are describing basic neurocomputer unit structure as well as linkage of these elements ...

Models of neural systems often use idealized inputs and outputs, but there is also much to learn by forcing a neural model to interact with a complex simulated or physical environment. Unfortunately, sophisticated interactions require models of large neural systems, which are difficult to run in real time. We have prototyped a system that can simulate efficient surrogate models of a wide range ...

To meet the requirements of micro-grid real-time simulation, a novel real-time simulator for micro-grids based on Field-Programmable Gate Array (FPGA) and orders (FO-RTDS) is designed. We describe the design idea of the real-time solver and the order generator. Multi-valued parameter prestorage and multi-rate simulation are introduced to reduce the computational pressure. The data scheduling is...

Eye state recognition is one of the main stages of many image processing systems such as driver drowsiness detection system and closed-eye photo correction. Driver drowsiness is one of the main causes in the road accidents around the world. In these circumstances, a fast and accurate driver drowsiness detection system can prevent these accidents. In this article, we proposed a fast algorithm fo...

In this paper, a new controllable V-shape multiscroll attractor is presented, where a variety of symmetrical and unsymmetrical attractors with a variable number of scrolls can be controlled using new staircase nonlinear function and the parameters of the system. This attractor can be used to generate random signals with a variety of symbol distribution. Digital implementation of the proposed ge...

Electronic design tools and techniques for the implementation of a stereoscopic camera based on an FPGA (Field Programmable Gate Array) are presented. The stages of an IPP (Image Processing Pipeline) are presented together with the development tools and languages used to implement a stereoscopic camera in hardware. In a further development of the basic system, aspects of the implementation of a...

In this paper, we present a coprocessor to accelerate explicit state based model checking by computing the set of reachable states with the help of massively parallel hardware. The algorithm is based on known implementations of algorithms for the solution of the algebraic path problem on systolic arrays. We describe the mapping to a field programmable gate array, including the implementation of...

As any well-designed information security application uses a very large quantity of good pseudorandom numbers, inefficient generation of these numbers can be a significant bottleneck in various situations. In previous research works, a technique that applies welldefined discrete iterations, satisfying the reputed Devaney’s definition of chaos, has been developed. It has been proven that the gen...
