Ask lecturer/engineers whenever have any problems related with the subject. 8 The First Computer The Babbage Difference Engine (1832) 25,000 parts cost: £17,470 9 ENIAC - The first electronic computer (1946) 10 The Transistor Revolution First transistor Bell Labs, 1948 11 The First Integrated Circuits Bipolar logic 1960’s ECL 3-input Gate Motorola 1966 12 Intel 4004 Micro-Processor 1971 1000 transistors 1 MHz operation 13 Moore’s Law In 1965, Gordon Moore noted that the number of transistors on a chip doubled every 18 to 24 months. He made a prediction that semiconductor technology will double its effectiveness every 18 months 14 1959 1960 1961 1962 1963 1964 1965 1966 1967 1968 1969 1970 1971 1972 1973 1974 1975 LOG2 OF THE NUMBER OF COMPONENTS PER INTEGRATED FUNCTION Moore’s Law 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 15 Transistor Counts 16 Moore’s law in Microprocessors 17 Die Size Growth 18 Frequency 19 Scaling…. Technology shrinks by 0.7/generation With every generation can integrate 2x more functions per chip; chip cost does not increase significantly Cost of a function decreases by 2x But … How to design chips with more and more functions? Design engineering population does not double every two years… Hence, a need for more efficient design methods Exploit different levels of abstraction 20 Design Abstraction Levels 21 Design Metrics How to evaluate performance of a digital circuit (gate, block, …)? Cost Reliability Scalability Speed (delay, operating frequency) Power dissipation Energy to perform a function 22 Die Single Die Wafer 23 WHAT IS IC? IC Package ICs on PCB Wafer Inside IC 24 = IC Layout = IC Schematic 25 Why VLSI? Integration improves the design Lower parasitics = higher speed Lower power consumption Physically smaller Integration reduces manufacturing cost (almost) no manual assembly 26
