¡¡¡¡Today's digital technology£¬ computer technology have penetrated into various fields. The ability to master and apply computer technology has become one of the criten.a to measure the quality of a professional technicians. Assembly Language & Interfaang Technology is an important computer technology course in science and engineering of higher education.¡¡¡¡Although the rapid development of computer technology£¬ microprocessors have been from 32 to 64-bit transition£¬ for a variety of control systems£¬ we commonly use 8-bit£¬ 16-bit interface technology to meet the appli.cation requirements£¬ so 32 or even 64 microprocessor to explain the working principle of microcomputers is not suitable. This book is a 16-bit microprocessor model£¬ about the basic principles of computer and interface technology£¬ easy to learn and understand£¬ its basic concepts£¬ basic ideas and basic methods and 32-bit processor are the same.¡¡¡¡This book is mainly for the general colleges and universities of computer science£¬ electromechanical contror and non-electronics majors students. The preparation of this book focuses on theory with practice and engineering applications. In the preparation of teaching materials in the introduction oflife £¬a lot of examples witch are easy to understand are used to help readers understand the basic concepts of computer. After talking about the working pri.nciple of various interface chips£¬ the book g£ºives a number of examples which can be directly applied£¬ and give some different solutions to achieve the function.¡¡¡¡The book is divided into 7 chapters. Chapter 1 introduces the basics of comicrocomprter systems£» Chapter 2 introduces assembly language in graphical form£» Chapter 3 introduces the assembly language programming method£» Chapter 4 introduces the 16-bit processor Pins£¬ read and write timing£» Chapter 5 describes the I/O interface£¬ the basic composition£¬ read and write technology and data transfer£» Chapter 6 introduces the concept of interrupts and functions of programming 8259A chip. Chapter 7 introduces the internal structure and programming of the programmable parallel interface chip 8255A£¬ the serial interface chip 8251A£¬ and the timer/counter interface chip 8253/8254.¡¡¡¡This book is comprehensive£¬ and self-contained£¬ the assembly language prograrrurung part and the computer principle and interface technology are orgamied together£¬ through appropriate choice£¬ and is suitable both computer professional and non-computer professional students.¡¡¡¡This book is writen by Zeng Lanl.ing£¬ Han Xiaoru£¬ and Li chang£» Adjardiah Winffed Kudjo Patrick as deputy editors.¡¡¡¡The authors of this book in the process of writing referred to a lot of excellent reference materials£¬ thanks to the author of these materials£¬ in particular£¬ thanks especially to Ma Weihua£¬ Qian Xiajie and Yang Wenxian. In addition£¬ the writing of this book has been the national teaching quality engineering network of professional comprehensive reform project and Jiangsu University teaching reform project support.¡¡¡¡Due to the limitation of editors£¬ there are some errors and omission£¬ please critilize.
