This text is an introduction to the design and implementation of various types of system software. A central theme of the book is the relationship between machine architecture and system software.

Systems Software: Essential Concepts provides students with an accessible introduction to the knowledge and fundamentals that are necessary to understand software and hardware. The text also reviews implementation techniques to familiarize students with more complex software, such as operating systems and compilers, and prepare them to take more advance courses within the discipline. The book is divided into two key topical areas: compiler fundamentals and the basic mechanisms and data structures required to support operating systems. In the compiler section, students learn about the runtime environment, how to implement a scanner and a symbol table, and how to implement parsing and code generation for a virtual machine. To emphasize practical application, students are challenged to implement a small compiler. In the operating system domain, students gain an understanding of the interrupt mechanism, process and thread implementation, and process synchronization. Featuring a modern and practical approach, Systems Software is an ideal resource for courses in system programming, systems software, software development, and assembly language. It can also serve as a supplementary material for introductory operating system and compiler courses.

Intended as a text for the undergraduate students of Computer Science and Master of Computer Applications (MCA), this comprehensive yet concise book introduces the reader to the recent Intel 32-bit architecture, its programming and associated system programs. The text begins by giving an overview of major system software and proceeds to discuss the assembly language programming with a number of examples. Topics such as assemblers, linkers and microprocessor are dealt with using Netwide Assembler (NASM)—the free platform independent assembler to generate object code. All the stages of a compiler design, its important methodologies, and the recent design techniques of text editor along with the advance data structures used for this purpose are also covered in sufficient detail. Finally, the essential features of debuggers, their design techniques and, most importantly, the hardware and software support for designing a good debugger are described. KEY FEATURES : • Gives a fairly large number of examples and problems to help students in understanding the concepts better. • The text easily correlates theory with practice. • Provides exhaustive discussion on Netwide Assembler (NASM).

Computer software reliability has never been so important. Computers are used in areas as diverse as air traffic control, nuclear reactors, real-time military, industrial process control, security system control, biometric scan-systems, automotive, mechanical and safety control, and hospital patient monitoring systems. Many of these applications require critical functionality as software applications increase in size and complexity. This book is an introduction to software reliability engineering and a survey of the state-of-the-art techniques, methodologies and tools used to assess the reliability of software and combined software-hardware systems. Current research results are reported and future directions are signposted. This text will interest: graduate students as a course textbook introducing reliability engineering software; reliability engineers as a broad, up-to-date survey of the field; and researchers and lecturers in universities and research institutions as a one-volume reference.

“Don’s book is a very good addition both to the testing literature and to the literature on quality assurance and software engineering... . [It] is likely to become a standard for test training as well as a good reference for professional testers and developers. I would also recommend this book as background material for negotiating outsourced software contracts. I often work as an expert witness in litigation for software with very poor quality, and this book might well reduce or eliminate these lawsuits....” –Capers Jones, VP and CTO, Namcook Analytics LLC Software and system testers repeatedly fall victim to the same pitfalls. Think of them as “anti-patterns”: mistakes that make testing far less effective and efficient than it ought to be. In Common System and Software Testing Pitfalls, Donald G. Firesmith catalogs 92 of these pitfalls. Drawing on his 35 years of software and system engineering experience, Firesmith shows testers and technical managers and other stakeholders how to avoid falling into these pitfalls, recognize when they have already fallen in, and escape while minimizing their negative consequences. Firesmith writes for testing professionals and other stakeholders involved in large or medium-sized projects. His anti-patterns and solutions address both “pure software” applications and “software-reliant systems,” encompassing heterogeneous subsystems, hardware, software, data, facilities, material, and personnel. For each pitfall, he identifies its applicability, characteristic symptoms, potential negative consequences and causes, and offers specific actionable recommendations for avoiding it or limiting its consequences. This guide will help you Pinpoint testing processes that need improvement–before, during, and after the project Improve shared understanding and collaboration among all project participants Develop, review, and optimize future project testing programs Make your test documentation far more useful Identify testing risks and appropriate risk-mitigation strategies Categorize testing problems for metrics collection, analysis, and reporting Train new testers, QA specialists, and other project stakeholders With 92 common testing pitfalls organized into 14 categories, this taxonomy of testing pitfalls should be relatively complete. However, in spite of its comprehensiveness, it is also quite likely that additional pitfalls and even missing categories of pitfalls will be identified over time as testers read this book and compare it to their personal experiences. As an enhancement to the print edition, the author has provided the following location on the web where readers can find major additions and modifications to this taxonomy of pitfalls: http://donald.firesmith.net/home/common-testing-pitfalls Please send any recommended changes and additions to dgf (at) sei (dot) cmu (dot) edu, and the author will consider them for publication both on the website and in future editions of this book.

An essential introduction to the analysis and verification of control system software The verification of control system software is critical to a host of technologies and industries, from aeronautics and medical technology to the cars we drive. The failure of controller software can cost people their lives. In this authoritative and accessible book, Pierre-Loïc Garoche provides control engineers and computer scientists with an indispensable introduction to the formal techniques for analyzing and verifying this important class of software. Too often, control engineers are unaware of the issues surrounding the verification of software, while computer scientists tend to be unfamiliar with the specificities of controller software. Garoche provides a unified approach that is geared to graduate students in both fields, covering formal verification methods as well as the design and verification of controllers. He presents a wealth of new verification techniques for performing exhaustive analysis of controller software. These include new means to compute nonlinear invariants, the use of convex optimization tools, and methods for dealing with numerical imprecisions such as floating point computations occurring in the analyzed software. As the autonomy of critical systems continues to increase—as evidenced by autonomous cars, drones, and satellites and landers—the numerical functions in these systems are growing ever more advanced. The techniques presented here are essential to support the formal analysis of the controller software being used in these new and emerging technologies.
