Amazon.com description: Product Description: This has become the standard book on the i860 covering all aspects of this new RISC (reduced instruction set computer) based microprocessor architecture. It is written in three distinct sections. Part I describes the evolution of the architecture of the i860 and the RISC philosophy. Part II, devoted to programming, is unique in that it contains explanations of why things are done, not just instructions on how to do them. Margulis also uses example programs to reinforce what he teaches. Part III provides in-depth reference material including full instruction sets, coding tips, and assembler information.
