The study of microprocessor architecture and programming is fundamental to many science and engineering branches including Computer Science/Engineering, Electronics Engineering, Electrical Engineering, Instrumentation and Control Engineering, M.Sc. in Electronics, M.Sc. in Information Technology and many more. This book is designed as a text for one semester course that covers microprocessor programming and architectures of advance processors. The book covers the architecture and programming of the popular Intel 16-bit microprocessor 8086 in depth; the architectural features of the 80286/386/486 processors; the protected mode software model of the 80386 including segmentation, protection, paging and multitasking; the technical overview of the Pentium family and finally overview of the RISC features with Sun SPARC overview.
