Assembly Language for X86 Processors

Assembly Language for x86 Processors, 6/e is ideal for undergraduate courses in assembly language programming and introductory courses in computer systems and computer architecture. Written specifically for the Intel/Windows/DOS platform, this complete and fully updated study of assembly language teaches students to write and debug programs at the machine level. Based on the Intel processor family, the text simplifies and demystifies concepts that students need to grasp before they can go on to more advanced computer architecture and operating systems courses. Students put theory into practice through writing software at the machine level, creating a memorable experience that gives them the confidence to work in any OS/machine-oriented environment. Proficiency in one other programming language, preferably Java, C, or C++, is recommended.

"This textbook [Irvine] teaches assembly and architecture fundamentals in a logical and concise manner for students with a reasonable CS1 backgrounds...and are applicable to higher-level programmers as to their understanding of what is happing to the code that they write and how it behaves during compilation and execution." -- John Doyle, Indiana University, Southeast "The problems and exercises are of good quality and quantity; they always have similarity within the chapter examples, but they are presented in a more challenging way. Students can pick-up skills that can be transferred to solving a new problem." -- Yinping Jiao, South Texas College "The book [Irvine] is well-organized. The chapters are lined-up such that after you cover the foundations presented in chapter 1-8, you can jump to any chapter you like consistent with what you think the students should know for upcoming classes." -- Remzi Seker, University of Arkansas, Little Rock "Wonderful!
