Assembly Language Programming for X86 Processors
What is Assembly Language?Each personal computer has a microprocessor that manages the computer's arithmetical, logical, and control activities.Each family of processors has its own set of instructions for handling various operations such as getting input from keyboard, displaying information on screen and performing various other jobs. These set of instructions are called 'machine language instructions'.A processor understands only machine language instructions, which are strings of 1's and 0's. However, machine language is too obscure and complex for using in software development. So, the low-level assembly language is designed for a specific family of processors that represents various instructions in symbolic code and a more understandable form.Advantages of Assembly LanguageHaving an understanding of assembly language makes one aware of −How programs interface with OS, processor, and BIOS;How data is represented in memory and other external devices;How the processor accesses and executes instruction;How instructions access and process data;How a program accesses external devices.Other advantages of using assembly language are −It requires less memory and execution time;It allows hardware-specific complex jobs in an easier way;It is suitable for time-critical jobs;It is most suitable for writing interrupt service routines and other memory resident programs.
Assembly Language for x86 Processors
This is the eBook of the printed book and may not include any media, website access codes, or print supplements that may come packaged with the bound book. 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.
