Calculation is the main function of a computer. The central unit is responsible for executing the programs. The microprocessor is its integrated form. This component, since the announcement of its marketing in 1971, has not stopped breaking records in terms of computing power, price reduction and integration of functions (calculation of basic functions, storage with integrated controllers). It is present today in most electronic devices. Knowing its internal mechanisms and programming is essential for the electronics engineer and computer scientist to understand and master the operation of a computer and advanced concepts of programming. This first volume focuses more particularly on the first generations of microprocessors, that is to say those that handle integers in 4 and 8-bit formats. The first chapter presents the calculation function and reminds the memory function. The following is devoted to notions of calculation model and architecture. The concept of bus is then presented. Chapters 4 and 5 can then address the internal organization and operation of the microprocessor first in hardware and then software. The mechanism of the function call, conventional and interrupted, is more particularly detailed in a separate chapter. The book ends with a presentation of architectures of the first microcomputers for a historical perspective. The knowledge is presented in the most exhaustive way possible with examples drawn from current and old technologies that illustrate and make accessible the theoretical concepts. Each chapter ends if necessary with corrected exercises and a bibliography. The list of acronyms used and an index are at the end of the book.

Primarily intended for diploma, undergraduate and postgraduate students of electronics, electrical, mechanical, information technology and computer engineering, this book offers an introduction to microprocessors and microcontrollers. The book is designed to explain basic concepts underlying programmable devices and their interfacing. It provides complete knowledge of the Intel’s 8085 and 8086 microprocessors and 8051 microcontroller, their architecture, programming and concepts of interfacing of memory, IO devices and programmable chips. The text has been organized in such a manner that a student can understand and get well-acquainted with the subject, independent of other reference books and Internet sources. It is of greater use even for the AMIE and IETE students—those who do not have the facility of classroom teaching and laboratory practice. The book presents an integrated treatment of the hardware and software aspects of the 8085 and 8086 microprocessors and 8051 microcontroller. Elaborated programming, solved examples on typical interfacing problems, and a useful set of exercise problems in each chapter serve as distinguishing features of the book.

Here's an entire learning solution in one book, complete with detailed coverage, questions, problems, and lab experiments! Microprocessor Architecture, Programming, and Systems Featuring the 8085 details the 8085 processor, from both a hardware and software standpoint. Readers will learn pseudo-code and flowcharting as tools in programming a microprocessor, with current, focused coverage that is perfectly written for the two-year college student. Comprehensive exposure to microprocessor architecture includes an entire chapter devoted to both the hardware and software of the 8051 Microcontroller not found in other books. Coverage also includes a uniquely thorough comparison of the 8085 microprocessor with other Motorola and Intel microprocessors.

The book is written for an undergraduate course on the 8086 microprocessor and 8051 microcontroller. It provides comprehensive coverage of the hardware and software aspects of 8086 microprocessor and 8051 microcontroller. The book is divided into three parts. The first part focuses on 8086 microprocessor. It teaches you the 8086 architecture, instruction set, Assembly Language Programming (ALP), interfacing 8086 with support chips, memory, and peripherals such as 8251, 8253, 8255, 8259, 8237 and 8279. It also explains the interfacing of 8086 with data converters - ADC and DAC and introduces a traffic light control system. The second part focuses on multiprogramming and multiprocessor configurations, numeric processor 8087, I/O processor 8089 and introduces features of advanced processors such as 80286, 80386, 80486 and Pentium processors. The third part focuses on 8051 microcontroller. It teaches you the 8051 architecture, instruction set, programming 8051 and interfacing 8051 with external memory. It explains timers/counters, serial port, interrupts of 8051 and their programming. It also describes the interfacing 8051 with data converters - ADC and DAC, keyboards, LCDs, LEDs, stepper motors, and sensors.
