Ebook: x86 Instruction Set Architecture

The Instruction Set Architecture, or ISA, is defined as that part of the processor architecture related to programming, including the native data types, instructions, registers, addressing modes, memory architecture, interrupt and exception handling, and external IO. With the exception of some small deviations and differences in terminology, all Intel and AMD x86 processors share a common ISA. This book focuses on those shared attributes (it does not cover those areas where the two companies have chosen widely divergent solutions which, by definition, fall outside of the ISA specification). If you re looking for a comprehensive book designed to bootstrap you up quickly on virtually all aspects of the x86 32/64-bit Instruction Set Architecture (ISA), we respectfully ask you to consider this book.
