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.

This hands-on tutorial is a broad examination of how a modern computer works. Classroom tested for over a decade, it gives readers a firm understanding of how computers do what they do, covering essentials like data storage, logic gates and transistors, data types, the CPU, assembly, and machine code. Introduction to Computer Organization gives programmers a practical understanding of what happens in a computer when you execute your code. You may never have to write x86-64 assembly language or design hardware yourself, but knowing how the hardware and software works will give you greater control and confidence over your coding decisions. We start with high level fundamental concepts like memory organization, binary logic, and data types and then explore how they are implemented at the assembly language level. The goal isn’t to make you an assembly programmer, but to help you comprehend what happens behind the scenes between running your program and seeing “Hello World” displayed on the screen. Classroom-tested for over a decade, this book will demystify topics like: How to translate a high-level language code into assembly language How the operating system manages hardware resources with exceptions and interrupts How data is encoded in memory How hardware switches handle decimal data How program code gets transformed into machine code the computer understands How pieces of hardware like the CPU, input/output, and memory interact to make the entire system work Author Robert Plantz takes a practical approach to the material, providing examples and exercises on every page, without sacrificing technical details. Learning how to think like a computer will help you write better programs, in any language, even if you never look at another line of assembly code again.

This comprehensive book provides an up-to-date guide to programming the Intel 8086 family of microprocessors, emphasizing the close relationship between microprocessor architecture and the implementation of high-level languages.

This textbook introduces readers to assembly and its role in computer programming and design. The author concentrates on covering the 8086 family of processors up to and including the Pentium. The focus is on providing students with a firm grasp of the main features of assembly programming, and how it can be used to improve a computer's performance. All of the main features are covered in depth: stacks, addressing modes, arithmetic, selection and iteration, as well as bit manipulation. Advanced topics include: string processing, macros, interrupts and input/output handling, and interfacing with such higher-level languages as C. The book is based on a successful course given by the author and includes numerous hands-on exercises.
