THE BOOK IS WRITTEN AS PER THE SYLLABUS of the subject of Microprocessor for T. E. (Computer Engineering), Semester V of University of Mumbai. Those topics that are related to the syllabus but not explicitly mentioned are included in the appendices. These are topics that students need to be familiar with, but are generally not asked in the theory examination. 8086 microprocessor is described in detail along with glimpses of 8088, 80186 and 80188 microprocessors. The various peripheral controllers for 8086/88 are also discussed. There is a recap at the end of each section, which summarizes the points discussed in the section. Exercises are given at the end of each chapter. University questions, objective questions and oral questions along with the answers are also included at the end of each chapter. KEY FEATURES — The book focuses on the three main aspects of the study of microprocessors – architecture, programming and system design. — The programs are given alongside the related theory for the convenience of the readers. The programs will help the students to prepare for the practical examination. — Both DOS-based programs as well as kit programs are given. — Algorithms and flowcharts are given before DOS-based programs for easy understanding of the program logic. — Comments are written at appropriate places in the programs.
