This book was released on 1988 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bring a Deeper Understanding of Systems to Software and System Development Originally titled On the Design of Stable Systems in its first, hardcover incarnation, in 1979, General Principles of Systems Design does not just focus on computer systems, but systems of all kinds--human, natural, and technological. In a highly readable, original presentation that embraces everything from depletion curves to the Feedback Principle (the method of controlling a system by reinserting it into the results of its past performance), the Weinbergs explore the subtle art and science of regulating systems, projects, and people in the most efficient and logical manner possible. The authors draw on their respective backgrounds in technology and social science to offer fresh insights and translate them into a language that anyone can understand. In the course of this presentation, the Weinbergs introduce a host of laws and theorems derived from the best thinking of systems thinkers over the past century. In addition to being a reference book for professional and lay people alike, General Principles of Systems Design is suitable as an undergraduate text in the humanities, social, natural, and engineering sciences. It is unique in its approach, highly readable, and offers practical ways of solving problems.

Available in PDF, EPUB and Kindle. Book excerpt: Principles of Computer System Design is the first textbook to take a principles-based approach to the computer system design. It identifies, examines, and illustrates fundamental concepts in computer system design that are common across operating systems, networks, database systems, distributed systems, programming languages, software engineering, security, fault tolerance, and architecture.Through carefully analyzed case studies from each of these disciplines, it demonstrates how to apply these concepts to tackle practical system design problems. To support the focus on design, the text identifies and explains abstractions that have proven successful in practice such as remote procedure call, client/service organization, file systems, data integrity, consistency, and authenticated messages. Most computer systems are built using a handful of such abstractions. The text describes how these abstractions are implemented, demonstrates how they are used in different systems, and prepares the reader to apply them in future designs.The book is recommended for junior and senior undergraduate students in Operating Systems, Distributed Systems, Distributed Operating Systems and/or Computer Systems Design courses; and professional computer systems designers. - Concepts of computer system design guided by fundamental principles - Cross-cutting approach that identifies abstractions common to networking, operating systems, transaction systems, distributed systems, architecture, and software engineering - Case studies that make the abstractions real: naming (DNS and the URL); file systems (the UNIX file system); clients and services (NFS); virtualization (virtual machines); scheduling (disk arms); security (TLS) - Numerous pseudocode fragments that provide concrete examples of abstract concepts - Extensive support. The authors and MIT OpenCourseWare provide on-line, free of charge, open educational resources, including additional chapters, course syllabi, board layouts and slides, lecture videos, and an archive of lecture schedules, class assignments, and design projects

Download or read book Embedded Systems Design with Platform FPGAs written by Ronald Sass and published by Morgan Kaufmann. This book was released on 2010-09-10 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: Embedded Systems Design with Platform FPGAs introduces professional engineers and students alike to system development using Platform FPGAs. The focus is on embedded systems but it also serves as a general guide to building custom computing systems. The text describes the fundamental technology in terms of hardware, software, and a set of principles to guide the development of Platform FPGA systems. The goal is to show how to systematically and creatively apply these principles to the construction of application-specific embedded system architectures. There is a strong focus on using free and open source software to increase productivity. Each chapter is organized into two parts. The white pages describe concepts, principles, and general knowledge. The gray pages provide a technical rendition of the main issues of the chapter and show the concepts applied in practice. This includes step-by-step details for a specific development board and tool chain so that the reader can carry out the same steps on their own. Rather than try to demonstrate the concepts on a broad set of tools and boards, the text uses a single set of tools (Xilinx Platform Studio, Linux, and GNU) throughout and uses a single developer board (Xilinx ML-510) for the examples. - Explains how to use the Platform FPGA to meet complex design requirements and improve product performance - Presents both fundamental concepts together with pragmatic, step-by-step instructions for building a system on a Platform FPGA - Includes detailed case studies, extended real-world examples, and lab exercises

Download or read book A Philosophy of Software Design written by John K. Ousterhout and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This book addresses the topic of software design: how to decompose complex software systems into modules (such as classes and methods) that can be implemented relatively independently. The book first introduces the fundamental problem in software design, which is managing complexity. It then discusses philosophical issues about how to approach the software design process and it presents a collection of design principles to apply during software design. The book also introduces a set of red flags that identify design problems. You can apply the ideas in this book to minimize the complexity of large software systems, so that you can write software more quickly and cheaply."--Amazon.

Download or read book Principles of Engineering Design written by Vladimir Hubka and published by Elsevier. This book was released on 2015-08-11 with total page 129 pages. Available in PDF, EPUB and Kindle. Book excerpt: Principles of Engineering Design discusses design applicability to machine systems, the nature and scope of technical processes, technical systems, machine systems, the human design engineer, the design process, and cases related to methods and procedures. The text deals with the structure, mode of action, properties, origination, development, and systematics of such technical systems. It analyzes the design process in terms of case problems, modelling, structure, strategies, tactics, representation, and working means. It also describes in detail the general model of a methodical procedure: separate design steps are treated in a unified fashion from different perspectives. The text notes that the tasks and methods of design research involve the following: (1) Components—determining structural elements in the design process; (2) Sequence—determining a general procedural model for the design process with a minimum of failures; (3) Modifications—what changes in factors affect the design process; and (5) Tactics—selection for individual design operations to obtain optimal results. A case study exemplifies the significant stages of design of a welding positioner. The book is highly recommended for students and the practicing design engineer in various fields.

This book was released on 2017-01-27 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyber-physical systems (CPS) are "engineered systems that are built from, and depend upon, the seamless integration of computational algorithms and physical components." CPS can be small and closed, such as an artificial pancreas, or very large, complex, and interconnected, such as a regional energy grid. CPS engineering focuses on managing inter- dependencies and impact of physical aspects on cyber aspects, and vice versa. With the development of low-cost sensing, powerful embedded system hardware, and widely deployed communication networks, the reliance on CPS for system functionality has dramatically increased. These technical developments in combination with the creation of a workforce skilled in engineering CPS will allow the deployment of increasingly capable, adaptable, and trustworthy systems. Engineers responsible for developing CPS but lacking the appropriate education or training may not fully understand at an appropriate depth, on the one hand, the technical issues associated with the CPS software and hardware or, on the other hand, techniques for physical system modeling, energy and power, actuation, signal processing, and control. In addition, these engineers may be designing and implementing life-critical systems without appropriate formal training in CPS methods needed for verification and to assure safety, reliability, and security. A workforce with the appropriate education, training, and skills will be better positioned to create and manage the next generation of CPS solutions. A 21st Century Cyber-Physical Systems Education examines the intellectual content of the emerging field of CPS and its implications for engineering and computer science education. This report is intended to inform those who might support efforts to develop curricula and materials; faculty and university administrators; industries with needs for CPS workers; and current and potential students about intellectual foundations, workforce requirements, employment opportunities, and curricular needs.

Download or read book Operating Systems written by William Stallings and published by Prentice Hall. This book was released on 2009 with total page 905 pages. Available in PDF, EPUB and Kindle. Book excerpt: For a one-semester undergraduate course in operating systems for computer science, computer engineering, and electrical engineering majors. Winner of the 2009 Textbook Excellence Award from the Text and Academic Authors Association (TAA)! Operating Systems: Internals and Design Principles is a comprehensive and unified introduction to operating systems. By using several innovative tools, Stallings makes it possible to understand critical core concepts that can be fundamentally challenging. The new edition includes the implementation of web based animations to aid visual learners. At key points in the book, students are directed to view an animation and then are provided with assignments to alter the animation input and analyze the results. The concepts are then enhanced and supported by end-of-chapter case studies of UNIX, Linux and Windows Vista. These provide students with a solid understanding of the key mechanisms of modern operating systems and the types of design tradeoffs and decisions involved in OS design. Because they are embedded into the text as end of chapter material, students are able to apply them right at the point of discussion. This approach is equally useful as a basic reference and as an up-to-date survey of the state of the art.
