Over the last ten years, the ARM architecture has become one of the most pervasive architectures in the world, with more than 2 billion ARM-based processors embedded in products ranging from cell phones to automotive braking systems. A world-wide community of ARM developers in semiconductor and product design companies includes software developers, system designers and hardware engineers. To date no book has directly addressed their need to develop the system and software for an ARM-based system. This text fills that gap. This book provides a comprehensive description of the operation of the ARM core from a developer´s perspective with a clear emphasis on software. It demonstrates not only how to write efficient ARM software in C and assembly but also how to optimize code. Example code throughout the book can be integrated into commercial products or used as templates to enable quick creation of productive software. The book covers both the ARM and Thumb instruction sets, covers Intel´s XScale Processors, outlines distinctions among the versions of the ARM architecture, demonstrates how to implement DSP algorithms, explains exception and interrupt handling, describes the cache technologies that surround the ARM cores as well as the most efficient memory management techniques. A final chapter looks forward to the future of the ARM architecture considering ARMv6, the latest change to the instruction set, which has been designed to improve the DSP and media processing capabilities of the architecture. No other book describes the ARM core from a system and software perspective. Author team combines extensive ARM software engineering experience with an in-depth knowledge of ARM developer needs.

Bachelor Thesis from the year 2009 in the subject Computer Science - Commercial Information Technology, grade: 1,3, University of Frankfurt (Main) (Institute of Information Systems), language: English, abstract: The Information Systems (IS) research discipline is undergoing a serious identity crisis, seeking its sphere of activity to be relevant in practice and rigorous in scientific considerations. One reason for this is the strengthening of the Design Science approach. This new discipline developed as a synergy from aspects of engineering, architecture, and industrial design and is employed in the design of IT artifacts and software systems. Design Science is becoming a powerful trend in IS research (Vahidov 2006). It gives the IS discipline a new and more detailed focal point as pertains to the application of software and IT artifact development which is growing in importance in IS research over the time (Weber 2003; Orlikowski and Iacono 2001; Cross 2001). IS practitioners ask for new and innovative design approaches, dealing with the evolving organizational and inter-organizational tasks. The way these tasks are executed, in close cooperation with the practical business world, seems to be insufficiently considered. The debate in IS research is carried out between traditional scientists and the knowledge-producing researchers/practitioners and ´´it could be argued that research aimed at developing IT systems, at improving IT practice, has been more successful and important than traditional scientific attempts to understand it´´ (March and Smith 1995, p. 252). IS researchers are mainly focused on the behavioral impact of new IT solutions within a business unit. These concepts are needed to describe the relationship between the humans and the technology. However, this way of conducting research is descriptive and evaluative. Instead of telling ´´what is´´ or ´´what will be´´, Design Science is giving guidance as to ´´how to do´´ things (Walls et al. 1992). The importance of this new approach is given through the rapid development of business needs and the increased necessity to solve business problems through the implementation of IT solutions. The knowledge base for designing new solutions has not yet been fully developed. IT consultants borrow knowledge from reference disciplines and apply this knowledge to present problems. This way of providing solutions is not compatible with Design Science as an area of research. A relevant design approach needs to give new answers to phenomena thus far unsolved. However, the IS discipline has not yet established a solid groundwork for Design Science within its discipline.

Digital Receipt System for Paperless Billing

The implementation of Radio Frequency Identification (RFID) technology in industrial manufacturing and retail supply chain management has seen strong growth in recent years. This is partly due to Wal-Marts RFID mandate to its suppliers. As more companies along the global supply chain adopt RFID, RFID tags embedded can be expected to proliferate in virtually every industrial product, ranging from computers to automobiles, in the near future. Large retailers likeWal-Mart and government agencies such as the U.S. Department of Defense (DoD) have driven recent developments in RFID technology. This in turn has a diffusion effect on hundreds of suppliers and manufacturers as their products are required to be tagged before shipping to these giant customers. RFID technology provides a good alternative to automatically reading and writing product information. In addition to recording the identity of an object, RFID technology also documents its current status, recent past, and immediate future. Using modern identification techniques, production systems can now produce variants of a product, or even different products, at a batch size of one. A product with an RFID tag can be viewed as an intelligent product. Several studies in this emerging field indicate the necessity of adopting new manufacturing approaches for making intelligent products. Digital receipt system is a conceptual prototype of paperless receipt. The basic idea is when we making a purchase with cash, magnetic card or RFID card the trisection information is automatically packaged & sent to a data base & store in it. This project can be implemented on any store like component store, medical store or at which we have to create & maintain the records of purchasing and sales of products.

This SpringerBrief introduces the development and practical application of a module-oriented development framework for domain specific system-dynamic libraries (SDL approach), which can be used in the simulation of multi-causal and dynamic relationships on different levels of an industry, as an example the construction industry. Multidisciplinary research and development teams, scientists from different domains as well as practitioners can develop SDL units from varying perspectives based on this approach. For example, the explanation of the risk situation of a company, the identification and evaluation of project risks, endangered operational procedures on various functional levels, or to improve the understanding of the decision making process in detail. This book is an excellent source for researchers, programmers and practitioners. It enables the development of suitable simulation systems from the beginning and demonstrates that it is possible to connect the development of simulation models and daily work. It provides advanced-level students from different domains with a comprehensive overview and clear understanding of a new and valuable modeling technique.

Diplomarbeit aus dem Jahr 2005 im Fachbereich Informatik - Wirtschaftsinformatik, Note: 1,3, Otto-Friedrich-Universität Bamberg (Fakultät Wirtschaftsinformatik und Angewandte Informatik), Veranstaltung: Wirtschaftsinformatik, Sprache: Deutsch, Abstract: Mit dieser Arbeit soll ein Werkzeug entworfen und implementiert werden, das die Modellbildung und die Simulation mit dem System-Dynamics-Ansatz auch für den gelegentlichen Nutzer von Standardsoftware zugänglich macht. Die zu erstellende Simulationsumgebung setzt sich aus einer Modellierungskomponente, die in einer anderen Arbeit parallel zu dieser entwickelt wird, und einer Simulations- und Auswertungskomponente, die Gegenstand dieser Arbeit ist, zusammen. In Kapitel 2 werden zunächst die Grundlagen dieser Arbeit vorgestellt. Aufbauend auf den systemtheoretischen Überlegungen, wird zunächst der Modellbegriff erläutert, bevor die Kybernetik und im Speziellen die Regelkreise in Bezug auf die System-Dynamics-Methode betrachtet werden. Abschließend wird eine Klassifizierung der einzelnen Methoden vorgenommen, wobei die kontinuierlichen Methoden genauer skizziert werden. Das 3. Kapitel beginnt mit einer allgemeinen Betrachtung des System-Dynamics-Ansatzes und widmet sich anschließend den qualitativen und quantitativen Ausprägungen der Methode. Dabei wird im Besonderen auf die mathematischen Eigenschaften des Ansatzes Bezug genommen. Im 4. Kapitel wird das Vorgehen bei der Entwicklung der Simulationsumgebung skizziert. Kapitel 5 betrachtet die Designentscheidungen in ihrer softwaretechnischen Implementierung. Dazu werden die einzelnen Systemkomponenten nacheinander eingehend analysiert und erläutert. Kapitel 6 bildet mit Fazit und Ausblick den Abschluss dieser Arbeit.
