Computers were originally invented to solve all sort of mathematical problems. Nowadays, computers do much more than that and are present in all human activities. In fact, a computer is a fantastic machine capable of doing the most amazing tasks, if an appropriate program is provided. A computer system contains hardware and system software that work together to run software applications. Interestingly, the underlying concepts that support the construction of a computer are relatively stable. In fact, (almost) all computer systems have a similar organisation, i.e., their hardware and software components are arranged in hierarchical layers and perform similar functions. This book was written for programmers and software engineers who want to comprehend how the components of a computer work and how they affect the correctness and performance of their programs.

Computers were invented to “compute“, i.e., to solve all sort of mathematical problems. A computer system contains hardware and systems software that work together to run software applications. The underlying concepts that support the construction of a computer are relatively stable. In fact, (almost) all computer systems have a similar organization, i.e., their hardware and software components are arranged in hierarchical layers (or levels) and perform similar functions. This book is written for programmers and software engineers who want to understand how the components of a computer work and how they affect the correctness and performance of their programs.

A new edition of a textbook that provides students with a deep, working understanding of the essential concepts of programming languages, completely revised, with significant new material. This book provides students with a deep, working understanding of the essential concepts of programming languages. Most of these essentials relate to the semantics, or meaning, of program elements, and the text uses interpreters (short programs that directly analyze an abstract representation of the program text) to express the semantics of many essential language elements in a way that is both clear and executable. The approach is both analytical and hands-on. The book provides views of programming languages using widely varying levels of abstraction, maintaining a clear connection between the high-level and low-level views. Exercises are a vital part of the text and are scattered throughout; the text explains the key concepts, and the exercises explore alternative designs and other issues. The complete Scheme code for all the interpreters and analyzers in the book can be found online through The MIT Press web site. For this new edition, each chapter has been revised and many new exercises have been added. Significant additions have been made to the text, including completely new chapters on modules and continuation-passing style. Essentials of Programming Languages can be used for both graduate and undergraduate courses, and for continuing education courses for programmers.

Essentials of Computer Organization and Architecture focuses on the function and design of the various components necessary to process information digitally. This title presents computing systems as a series of layers, taking a bottom-up approach by starting with low-level hardware and progressing to higher-level software. Its focus on real-world examples and practical applications encourages students to develop a "big-picture" understanding of how essential organization and architecture concepts are applied in the computing world. In addition to direct correlation with the ACM/IEEE guidelines for computer organization and architecture, the text exposes readers to the inner workings of a modern digital computer through an integrated presentation of fundamental concepts and principles. The Fifth Edition of Essentials of Computer Organization and Architecture was awarded the William Holmes McGuffey Longevity Award ("McGuffey") from the Text and Academic Authors Association (TAA). The McGuffy award recognizes textbooks and learning materials whose excellence has been demonstrated over time.

A hands-on approach to understanding and building compilers using the programming language Python. Compilers are notoriously difficult programs to teach and understand. Most books about compilers dedicate one chapter to each progressive stage, a structure that hides how language features motivate design choices. By contrast, this innovative textbook provides an incremental approach that allows students to write every single line of code themselves. Jeremy Siek guides the reader in constructing their own compiler in the powerful object-oriented programming language Python, adding complex language features as the book progresses. Essentials of Compilation explains the essential concepts, algorithms, and data structures that underlie modern compilers and lays the groundwork for future study of advanced topics. Already in wide use by students and professionals alike, this rigorous but accessible book invites readers to learn by doing. Deconstructs the challenge of compiler construction into bite-sized pieces Enhances learning by connecting language features to compiler design choices Develops understanding of how programs are mapped onto computer hardware Classroom-tested, hands-on approach suitable for students and professionals Extensive ancillary resources include source code and solutions
