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.

This text is intended to aid in the educational transition process from the sphere of discrete electronic technologies to the medium- and large-scale integration techniques used in the microprocessor field. The business manager or design engineer must weigh the cost of advanced technologies against the increased performance and marketability will find material of interest in the first three chapters. Components of microprocessor systems and the design of microprocessor memory systems are the focus of the seven subsequent chapters. The final five chapters focus on hardware, and machine level programming, using the Intel 8008 microprocessor machine language for the examples.
Short, concise, and easily-accessible, this book uses the 8085A microprocessor and 8051 microcontroller to explain the fundamentals of microprocessor architecture, programming, and hardware. It features only practical, workable designs so that readers can develop a complete understanding of the application with no frustrating gaps in the explanations. An abundance of real-life hardware, software, and schematic interpretation problems prepare readers to troubleshoot and trace signals through situations they will likely encounter on the job.
