High-performance computing refers to the use of advanced computing technologies, especially supercomputers, to solve highly complex, numerically intensive problems in the shortest possible time. Field programmable gate arrays (FPGAs) are emerging in many areas of high performance computing. FPGAs are so flexible and reconfigurable that they are capable of massively parallel operations, explicitly tailored to the problem at hand. There are many of paradigms to put FPGAs at work in a high performance computing environment. There are also many of limitations which restrict FPGAs to reach the performance of application Specific Integrated Circuits (ASICs) but they provide the possibility of changing the hardware design easily while outpacing software implementations on general purpose processors. Since FPGAs offer an inherently parallel computing paradigm The problem of achieving significant speedups on a new architecture without expending exorbitant development effort, while retaining flexibility, portability, and maintainability, is a classic one.

This is the era of automation. It is possible to alter the physical environment automatically through the use of computerized chips and protocols. The most basic use of this technology can be seen in the form of automated lights - the luminosity automatically turns on when a specific measurable level of darkness is crossed. At any level of luminosity above this, the lamps remain off. With Arduino, this has been made infinitely easier. Arduino produces single board microcontrollers which serve the purpose of a moderator/controller. Contained in the following pages is a detailed guide pertaining to the wonders of a microcontroller. It also covers the ways in which you can personalize it according to your specific needs. Keep reading to find out everything about Arduino

Neural networks have a proven ability to learn complex data sets, but suffer from the amount of processing time required for large based networks. FPGAs, which have become commonplace since their inception, offer the academic community a way of achieving real-time computation due to their parallel nature. Unfortunately, floating-point neural networks require large amounts of gate space, which in turn results in having to utilise an expensive FPGA. Fractional FPGA Neural Networks explores an alternative numeric system, where integer based fractions are used in the computations, rather than floating point. The book focuses on a number of issues and solutions with such a method, including modified training mechanisms. Finally, a case study of emotion recognition is explored. This book should be especially useful to academics seeking real-time computation networks, or even looking at alternative ideas for neural network design. Professionals in industry, exploring a practical solution to their data learning issues may also find the subject appealing, along with a wider community interested in researching into neural networks.
