Book Description

80486 System Architecture describes the hardware architecture of PC products using the Intel family of 80486 chips, providing a clear, concise explanation of the 80486 processor's relationship to the rest of the system. The author provides a comprehensive treatment of the processor including: -80486 microarchitecture and its functional units -internal and external caches -hardware interface -SL technology features -instructions new to the 80486 -the register set -486/487SX processors -486DX2 processors -486DX2 write-back enhanced processor -486DX4 processors -implementation-specific issues -main memory subsystem design -OverDrive processors If you design or test hardware or software that involves 486 processors, 80486 System Architecture is an essential, time-saving tool. The PC System Architecture Series is a crisply written and comprehensive set of guides to the most important PC hardware standards. Each title explains from a programmer's perspective the architecture, features, and operations of systems built using one particular type of chip or hardware specification. The PC System Architecture Series features step-by-step descriptions and instructions and accessible illustrations that enable a wide range of readers to easily understand difficult hardware topics. The authors, expert hardware training consultants for clients including IBM, Intel, Compaq, and Dell, have mastered the art of pinpointing and succinctly explaining just the critical information that PC programmers, software and hardware designers, and engineers need to know and leaving out the rest. The result is an exciting series of books that will enable readers of a wide range of backgrounds to make immediate gains in programming productivity.
