Assembly Language

Introduction to Assembly Language Programming

Assembly language continues to hold a core position in the programming world because of its similar structure to machine language and its very close links to underlying computer-processor architecture and design. These features allow for high processing speed, low memory demands, and the capacity to act directly on the system's hardware. This completely revised second edition of the highly successful Introduction to Assembly Language Programming introduces the reader to assembly language programming and its role in computer programming and design. The focus is on providing readers with a firm grasp of the main features of assembly programming, and how it can be used to improve a computer's performance. The revised edition covers a broad scope of subjects and adds valuable material on protected-mode Pentium programming, MIPS assembly language programming, and use of the NASM and SPIM assemblers for a Linux orientation. All of the language's main features are covered in depth. The book requires only some basic experience with a structured, high-level language. Topics and Features: Introduces assembly language so that readers can benefit from learning its utility with both CISC and RISC processors [ NEW ].- Employs the freely available NASM assembler, which works with both Microsoft Windows and Linux operating systems [ NEW ].- Contains a revised chapter on "Basic Computer Organization" [ NEW].- Uses numerous examples, hands-on exercises, programming code analyses and challenges, and chapter summaries.- Incorporates full new chapters on recursion, protected-mode interrupt processing, and floating-point instructions [ NEW ]. Assembly language programming is part of several undergraduate curricula in computer science, computer engineering, and electrical engineering. In addition, this newly revised text/reference can be used as an ideal companion resource in a computer organization course or as a resource for professional courses.

Computer Organization and Assembly Language Programming

Computer Organization and Assembly Language Programming deals with lower level computer programming-machine or assembly language, and how these are used in the typical computer system. The book explains the operations of the computer at the machine language level. The text reviews basic computer operations, organization, and deals primarily with the MIX computer system. The book describes assembly language programming techniques, such as defining appropriate data structures, determining the information for input or output, and the flow of control within the program. The text explains basic I/O programming concepts, technique of interrupts, and an overlapped I/O. The text also describes the use of subroutines to reduce the number of codes that are repetitively written for the program. An assembler can translate a program from assembly language into a loader code for loading into the computer's memory for execution. A loader can be of several types such as absolute, relocatable, or a variation of the other two types. A linkage editor links various small segments into one large segment with an output format similar to an input format for easier program handling. The book also describes the use of other programming languages which can offer to the programmer the power of an assembly language by his using the syntax of a higher-level language. The book is intended as a textbook for a second course in computer programming, following the recommendations of the ACM Curriculum 68 for Course B2 "Computers and Programming.
