  1. What is About This Course? 微電腦系統Microcomputer System

  2. You Must Know These Terms • Computer（電腦） • Microcomputer（微電腦） • Microprocessor（微處理器） • Microcontroller（微控制器） • Single Chip Computer（單晶片） • System-on-a-chip（系統單晶片，SoC） • Embedded System（嵌入式系統）

  3. What is Microcomputer? Micro + Computer

  4. HP tablet PC Computers ! microcomputer An IBM 704 mainframe PDP 7 minicomputer

  5. What is “Computer”? • Mainframe, minicomputer, supercomputer, personal computers, notebooks, tablet PC, workstations, super computers… • General-purpose • You can run games, editors, browsers etc. depend on the programs loaded in the memory. • High performance • Computers use very powerful CPUs. • Ex: Intel Core i7 920 has 4 cores.

  6. What is “Microcomputer”? • Microcomputer≈ Personal Computer • Microcomputers usually occupy physically small amounts of space when compared to mainframe and minicomputers.

  7. In this course"Microcomputer Systems", we want to tell you how microcomputers work!

  8. How Personal computer works? • What are included in a computer? • CPU, ROM, RAM,I/O controller, buses and many other chips are found in the motherboard. • Connect to many I/O devices

  9. “CPU” vs. “Microprocessor” • A microcomputer is a computer with a microprocessor as its CPU. • Central Processing Unit In 2008, the die of Conroe Core 2 Duo in Intel processor

  10. Famous Microprocessors • Intel • x86: 8086, 80286, 80386, 80486, Pentium • Merom, Conroe, Woodcrest • Core i3, Core i5 2500 4 core, Core i7, … • AMD • Sempron 145 AM3, Llano APU A6-3650 • A8-3850, A6-3650 4 cores, Phenom II • Motorola • 68000

  11. Do they need a microprocessor as its CPU? 微電腦洗衣機, 微電腦全自動豆漿機 微電腦電子鍋, 微電腦馬桶座? 微電腦電冰箱、微電腦冷氣機、電梯、遙控器、電話、手機…

  12. Some Products (1/2) • Security systems • Sensor, motion detector , power detector, smoke detector • Audio alarm, user authentication • Whitegoods and Household Appliances • Ref: http://www.maxim-ic.com/solutions

  13. Some Products (2/2) • MP3 player • standalone hard-wired MPEGI/II Layer-3 decoder with C51 microcontroller core handling dataflow control and MP3-player control • Smart card reader • USB controller • Ref: http://www.atmel.com/products/MP3/

  14. Systems with a Specific Function • Not high performance, low cost, small size, customized, automatic & smartcontrol • Don't need microprocessors. • Industry controllers/Intelligent appliances • Anti-lock braking system (ABS), automatic four-wheel drive, door opener. • Printer, keyboard, keyless entry, copier, fax machine, personal digital assistants (PDAs) • Video game player, camera, cellular phone, microwave, DVD player

  15. They need a simple and cheap CPU, small size RAM & ROM, more special I/Os (ex: temperature senor) --- Cost is most important! ---

  16. Single Chip Computer • How to cost down? • Answer: SoC (System on a Chip) • Contrary to computers, in which microprocessors, extra RAM & ROM, buses and I/Os are separate and put on a mother board, • these products uses single chip computers. • Single Chip Computer: All in one chip (CPU, I/O, ROM, RAM together.) • Or, it is called as microcontroller.

  17. What is “Microcontroller”? • A microcontroller (also microcontroller unit, MCU or µC) is a small computeron a single integrated circuit (IC) consisting of a relatively simple CPU combined with support functions such as a crystal oscillator, timers, watchdog, serial and analog I/O etc.

  18. Intel 8051 • In 1981, Intel MCU-51 • A single chip microcontroller (µC) • Used in embedded systems

  19. Intel 8742 Microcontroller • All functions on a chip • 128 bytes of RAM • 2048 bytes of EPROM • Input/Output • 8-bit microcontroller (12MHz)

  20. Microprocessor & Microcontroller • A micro-processor • a very powerful CPU • Usually, used for computer systems • Example: x86, 68K, z80 • A micro-controller (µC) • A simple computer system-on-a-chip • It contains a processor core, memory, and programmable input/output peripherals. • Example: 8048, 8051

  21. What is Embedded System? As shown in before slides, except for computers, other products with specific-function are embedded systems.

  22. What is “Embedded System”? • An embedded product uses a microprocessor or microcontroller to do one task only. • This is, it is a special-purpose product. • In an embedded system, there is only one application software that is typically burned into ROM. • Embedded system means the processor is embeddedinto that application.

  23. How Embedded System Works? • In general, an embedded system has • A microcontroller (mC) • I/O devices • A small board with a microcontroller, some components and I/O connectors • Real-time Operating System (RTOS) • Simple-function, small-size • Application software

  24. Goal of This Course (1/2) • The course “Computer Science” has taught us about complicated computer systems. • In this course, we will focus on “microcontroller” although this course is called “Microcomputer System”. • The design concepts are the same. • However, microcontrollers are much simpler than microcomputers such that we can discuss more detailed design.

  25. Goal of This Course (2/2) • Understand the architecture of 8051. • Leaning 8051 programming. • Prepare for the 8051 laboratory. • 8051 is a microcontroller. • 1981, Intel MCS-51 • Microcontroller: • A smaller computer • On-chip RAM, ROM, I/O ports... • Single-purpose

  26. Why Choose 8051? • Simple, easy to learn • A lot of 8051 users • After learning 8051, we can understand: • A basic concept of an embedded system • A simplest computer architecture • How micro-computer works. • Low-level language: Assembly Language

  27. 8051 Family • The 8051 became popular after Intel allowed other manufacturers to make and market an flavor of the 8051. • different speed, amount of on-chip ROM or other memories, special functions • Code-compatible with the original 8051 • Atmel, Infineon Technologies, Maxim Integrated Products, NXP, Nuvoton, ST Microelectronics, Silicon Laboratories Texas Instruments and Cypress Semiconductor.
