The 80386/387 Architecture

A comprehensive guide to this new microprocessor, which will be standard equipment in the new IBM PC's and compatibles. The authors describe the 80386 and its numerical co-processor, the 80387, including machine organization, memory structure, and I/O and register design. Morse (who helped to design the Intel 8086 chip) and company explain all the details of the 80386's instruction set, the evolution of segmentation and what it's used for, how to make programs resistant to numerical errors, how to interface hardware to 80386/387 systems, plus new operating system features. The 80386/387 is expected to dramatically affect personal computing applications, from ordinary spreadsheets to games to computer-aided drafting and artificial intelligence.
