Продукт закінченийview

This comprehensive textbook provides a systems-level understanding of the 80x86 microcomputer, essential for designers of microprocessor-based electronic equipment. It offers thorough, balanced, and practical coverage of both software and hardware topics related to the 8088 and 8086 microprocessors, extending to the 32-bit versions of the 80x86 family.

The book details how to assemble, run, and debug programs, and how to build, test, and troubleshoot interface circuits. It includes in-depth coverage of floating-point processing and the Single Instruction Multiple Data (SIMD) processing capability of advanced Pentium processors. Additional material covers number systems, logic functions, operations, conversions between number systems, and binary addition/subtraction.

New advanced topics include Floating Point Architecture and Instructions, Multimedia (MMX) Architecture and Instructions, and the hardware architecture of the Pentium 3 and Pentium 4 processors. The text covers Intel architecture microprocessor families: 8088, 8086, 80286, 80386, 80486, and the latest Pentium® processors. It illustrates DEBUG program commands for assembling, disassembling, loading, saving, executing, and debugging programs on the IBM PC, and introduces the 8088's instruction set. Practical implementation techniques, including the use of latches, transceivers, buffers, and programmable logic devices in memory and I/O interfaces, are also explored.

This volume serves as a valuable handbook for self-study in microprocessors, and is suitable for electrical engineers, electronic technicians, and computer programmers.

Software Architecture and Programming

Part I of the book delves into the software architecture of the 8088 and 8086 microprocessors. It guides the reader on how to write, execute, and debug assembly language programs. This section includes numerous practical concepts and software applications, exploring the various steps of the assembly language program development cycle.

Key Learning Areas:

• Software Architecture: Understanding internal registers, flags, memory organization, and stack from a software perspective.
• Software Development Tools: Utilizing debugger commands (e.g., DEBUG) to assemble, execute, and debug instructions and programs.
• Набір інструкцій: Learning the function of each instruction, permissible operand variations, and statement writing.
• Programming Techniques: Basic techniques such as flowcharting, jumps, loops, strings, subroutines, and parameter passing.
• Застосування: Step-by-step process for writing programs for practical applications, including block move routines.

The software section incorporates practical concepts and applications, demonstrating 32-bit addition/subtraction, bit masking, and the use of branch and loop operations for IF-THEN-ELSE, REPEAT UNTIL, and WHILE-DO program structures. The study of software architecture and assembly language programming is closely integrated with the use of the DEBUG program on the PC, and the Microsoft MASM Assembler is also covered for creating, assembling, and debugging programs.

Hardware Architecture and Interfacing

Part II examines the hardware architecture of microcomputers built with the 8088 and 8086 microprocessors. It provides a detailed understanding of the function and operation of each microprocessor's hardware interfaces: memory, input/output, and interrupt. The role of each subsystem in overall microcomputer system operation is thoroughly explored.

Key Hardware Topics:

• Microprocessor Architecture: Pin layout, minimum and maximum mode signal interfaces, signal functions, and clock requirements for 8088 and 8086.
• Memory and I/O Interfaces: Extensive coverage of bus cycles, address maps, interface circuits (latches, buffers, transceivers, decoders), programmable logic devices for bus-control logic, and I/O instructions.
• Memory Subsystems: Devices and circuits for program storage (ROM, PROM, EPROM, FLASH), data storage (SRAM, DRAM), and cache memory. Includes bus interface circuit and memory subsystem design techniques like parity-checker/generator and wait-state generator circuitry.
• Input/Output Interface Circuits: Detailed studies of discrete parallel I/O circuits, 82C55A, 8254, and 82C37A peripheral ICs. Exploration of special-purpose peripheral ICs and interfaces, such as serial communication with 8250/16450 UART controllers and keyboard/display driving with the 8279 controller.
• Переривання: Introduction to context switching, priority, interrupt vectors, interrupt vector table, interrupt acknowledge bus cycle, and interrupt service routines. External hardware interrupt interface circuits using discrete circuitry and the 82C59 programmable interrupt controller. Covers software interrupts, nonmaskable interrupts, reset operation, and internal interrupt processing.

The book also includes a study of the 8088-based microcomputer design used in the IBM PC, demonstrating practical implementation of microcomputer interfacing techniques. Material on hardware includes interface circuit operation, design, and troubleshooting, with examples for polling switches, lighting LEDs, scanning displays and keyboards, and printing characters.

Advanced Microprocessors and Future Trends

Part III provides detailed coverage of other microprocessors in the 80x86 family, including the 80286, 80386, 80486, and Pentium processors. The focus is on how their software and hardware architectures differ from earlier family members.

Advanced Topics Covered:

• DISC, CRISP, and superscaler processor architectures.
• Real-mode and protected-mode operation.
• Burst, pipelined, and cached bus cycles.
• Virtual memory, instruction set extensions, and system control instructions.
