  3. Course Overview • Syllabus Review • Let’s Go Over the Syllabus • Special issues this quarter • From Syllabus • Grading Policy • From Syllabus Lecture 1 - Introduction

  4. Historical Perspective • Late 60’s – 4 bit calculator chips • 1972 – 4040, 8080, 6800 (6 mo later) ~$300 • 1974,75 – Intel 8085, Zilog Z80 ~$300 • 1975 – MOS Technology 6502 ~$25 • 1975,76 – TI 9900 (16 bit processor) • 1978 – Intel 8086 – 16MHz ~ $3.95 • 1979 – Motorola 68000 – 12 MHz ~$12.95 • 1983,84 – Motorola 68020 – 16 MHz ~$39.95 Lecture 1 - Introduction

  5. Architecural Evolution • 4 bit internal – 4 bit data bus – 8 bit address • 8 bit internal – 8 bit data bus – 16 bit address • 16 bit internal – 8 bit data bus – 20 bit address • 16 bit internal – 16 bit data bus – 22 bit addr • 32 bit internal – 16 bit data bus – 24 bit addr • 32 bit internal – 32 bit data bus – 28 bit addr • 64 bit internal – 32 bit data bus – 32 bit addr • 64 bit internal – 64 bit data bus – 32 bit addr • 128 bit internal?????? and the future ????? Lecture 1 - Introduction

  6. Prices • 1992 • MC68000L8 - $7.95 – 8MHz • MC68010L10 - $12.95 – 10 MHz • MC6809 - $3.95 – 2 MHz • 2006 data • MC6809 - $3.95 – 2 MHz • MC68000L8 - $8.95 – 8 MHz • Intel Pentium - $28.05 – 166 MHz • Intel Celleron Dual Core 1.66GHz, 512Cache - $40 • Intel Core2Duo 3GHz 6MBcache 1.3GHz FSB - $180 • Today • Core2Duo,3GHz,6MB cache,1.3GHz FSB - $170 • Core2Quad,2.5GHz,4MB cache,1.3GHz FSB - $150 Lecture 1 - Introduction

  7. And the price for memory • In the 1970s • A 16 MB memory card for a TMS 80 (max memory 64 MB) was $200.00 • Today • DDR2 2G Memory DIMM – 800MHz - $30 • DDR3 2G Memory DIMM– 1.333MHz - $50 • 8 G Byte MMC memory card - $20 to $30 Lecture 1 - Introduction

  8. Applications and use • General Purpose PCs and Workstations • Scientific/Engineering • Computer Automated Manufacturing Equip • Robotic Control Systems • Medical Equipment • Business Computers and point of sale systems • Desktop Publishing • Data Communications and Networking • Automotive uses • Microwave ovens, Stoves, dishwashers, refrigerators, Lecture 1 - Introduction

  9. Course Goals • Understand more advanced micro-computer architecture concepts through the study of a representative architecture. • The 68000 family is one of several microprocessor families available. It has a relatively simple instruction set and representative interfacing capabilities. It also supports multitasking. Lecture 1 - Introduction

  10. Some basic definitions • Microprocessor – a single CPU on a single IC chip. Contains both control and RALU • Does not have on chip memory, timers, or I/O ports • Microcomputer – uProcessor with memory, I/O, timing, control, interfaces, powersupply • RALU – Register/Arithmetic Logic Unit Lecture 1 - Introduction
