Praised by experts for its clarity and thoroughness, this visually appealing, one-stop reference on PC"s uses a step-by-step approach to examining the fundamentals of 80x86 assembly language programming and PC architecture. Offering readers a real "hands-on" experience, it uses the Debug utility to show what action the instruction performs, then provides a sample program to show its application. Its oversized pages delve into dozens of related subjects, including DOS memory map, BIOS, microprocessor architecture, supporting chips, buses, interfacing techniques, system programming, memory hierarchy, DOS memory management, tables of instruction timings, hard disk characteristics, and more.Covers all the x86 microprocessors, from the 8088 to the Pentium Pro, and combines assembly and C programming early on. Introduces the x86 instructions with examples of how they are used, and uses fragments of programs from IBM PC technical reference to show a real-world approach to programming in assembly. Ensures a basic understanding of binary and hex numbering systems before delving into PC assembly language and system programming, and discusses hardware differences among 8086, 286, 386, 486, Pentium and Pentium Pro chips. Second Edition covers the latest in bit-manipulation, interrupt programming, mouse programming in assembly and C, INT 16H and key press detection, and DRAM technologies of EDO, SDRAM, and RAM BUS. Readers will also explore PC interfacing with real world devices such as LCD, stepper motor, ADC, DAC, and temperature Sensor.
