Computer Systems

Computer Systems, Second Edition provides students with a broad understanding of all levels of computer systems. It emphasizes computer science topics that are related to, but not usually included in, the treatment of hardware and its associated software. The topics are presented through a unified concept of computer systems. The book allows students to explore several levels, such as high-order languages, machine, assembly, and logic gate through a top-down approach.

Computer Systems, Second Edition covers the core topics in the Architecture and Organization category of the ACM and IEEE Curriculum 2001 Guidelines for Computer Science. This comprehensive approach supplies students with a fundamental understanding of computer systems.

• The Pep/7 Assembler and Simulator features an integrated text editor for the MSWindows and MacOS versions, along with error messages in red type that are inserted in the source code at the place where the error is detected. Pep/7 employs a student-friendly machine language object code in hexadecimal format, the ability to code directly in machine language, bypassing the assembler, and the ability to redefine the mnemonics for the unimplemented opcodes that trigger synchronous interrupts.
• Teaches the levels of abstraction, necessary for understanding computer systems, by using real world objects and concepts such as art, business and government, making difficult concept both understandable and memorable.
• The text is based on a virtual computer that is designed to teach the basic concepts of the classic von Neumann machine.
• Provides a framework for thinking about computer organization that prepares students for future courses in Automata Theory, Operating Systems, Advanced Computer Architecture, and beyond.
• Provides a thorough description of the IEEE floating point standard, including the special values NaN, infinity, and denormalized numbers. Problems have been added for students to implement floating point instructions using the interrupt mechanism of the virtual hardware.
