Research ArticleOpen accessIn the abstractDesign of a Distributed Control System Using a Personal Computer and Micro Control Units for Humanoid RobotsMitsuhiro Yamano, Akihiro Ochiai, Yuichi Suzukawa et al.Problem statement: Humanoid robots have many motors and sensors and many control methods are used to carry out complicated tasks of the robots. Therefore, efficient control systems are required for the robots. Approach: This study presented a distributed control system using a Personal Computer (PC) and Micro Control Units (MCUs) for humanoid robots. Distributed control systems have the advantages that … …Journal of Computer Science, Vol. 6, Issue 8 · 31 Aug 2010 · 7,525 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Field Programmable Gate Array Implementation of Basic Building Blocks for Power-Efficient Baugh-Wooley MultipliersMuhammad H. Rais, Bandar M. Al-Harthi, Saad I. Al-Askar, Fahad K. Al-HusseinProblem statement: As growing demands on portable computing and communication systems, the power-efficient multipliers play an important role. In these multipliers basic multiplication follows the Baugh-Wooley algorithms and can easily be implemented using Field Programmable Gate Array (FPGA) devices because the development cost for Application Specific Integrated Circuits (ASICs) are high. These algorithms should be verified and optimized before implementation. … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,123 accessesView PDFCite

In this study, a mathematical black-box model is developed and system identification techniques are combined with adaptive system techniques, to construct the Neuro-Identifier. Approach: The Neuro-Identifier was discussed as a black-box model to attack the target cipher … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 7,941 accessesView PDFCite
Research ArticleOpen accessIn the abstractField Programmable Gate Array -Based System-on-Chip for Real-Time Power Process ControlAhmed Karim Ben Salem, Slim Ben Othman, Slim Ben SaoudProblem Statement: Nowadays Real-Time (RT) embedded control applications require not just higher performance but more flexibility as well without increasing cost and resources. Approach: In this study we presented a promising co-design and implementation of control solution. We developed flexible solution using software control algorithms coupled with an embedded RT kernel on powerful embedded processor cores, combined with reconfigurable logic … …American Journal of Applied Sciences, Vol. 7, Issue 1 · 31 Jan 2010 · 7,455 accessesView PDFCite
Research ArticleOpen accessIn the abstractSolving the State Assignment Problem Using Stochastic Search Aided with Simulated AnnealingWalid M. AlyProblem statement: Solving the state assignment problem means finding the optimum assignment for each state within a sequential digital circuit. These optimum assignments will result in decreasing the hardware realization cost and increasing the reliability of the digital circuit. Unfortunately, the state assignment problem belongs to the class of nondeterministic polynomial time problems (NP complete) which requires heavy computations. Different … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 6,966 accessesView PDFCite
Research ArticleOpen accessIn the abstractMulti Microkernel Operating Systems for Multi-Core ProcessorsRami MatarnehProblem statement: In the midst of the huge development in processors industry as a response to the increasing demand for high-speed processors manufacturers were able to achieve the goal of producing the required processors, but this industry disappointed hopes, because it faced problems not amenable to solution, such as complexity, hard management and large consumption of energy. These problems forced … …Journal of Computer Science, Vol. 5, Issue 7 · 31 Jul 2009 · 7,547 accessesView PDFCite
