key Start with the highest possible level of abstraction e g control algorithms Establish properties at the right level Use formal models Leverage multiple scientific disciplines Establish horizontal and vertical supplier chain like partnerships Need change in education 5 Course overview Managing Complexity Orthogonalizing concerns Behavior Vs Architecture Computation Vs Communication 6 Behavior Vs Architecture Models of Computatio n 1 System 2 Architecture System Behavior Behavior Simulation Synthesis Performance models Emb SW comm and comp resources HW SW partitioning Scheduling Mapping 3 Performance Simulation Communication Refinement SW estimation 4 Flow To Implementation 7 Behavior Vs Communication Clear separation between functionality and interaction model Maximize reuse in different environments change only interaction model ETROPOLIS PIG Protocol interface generation PEARLS Latency insensitive protocols 8 Outline of the course Part 1 Introduction Future of Information

Information Technology Embedded Systems Automotive Home Networks Smart Dusts Universal Radios What is Needed at the Infrastructure Level High Leverage System Design Paradigms Communication based Design Architecture Function Co design Platform based Design as Implementation Technology 10 Electronics and the Car More than 30 of the cost of a car is now in Electronics 90 of all innovations will be based on electronic systems 11 Information Technology Scenario According to the International Data Corporation 96 of all Internet access devices shipped in the United States in 1997 were PCs By the end of 2002 nearly 50 will not be PCs Instead they will be digital set top boxes cell phones and personal digital assistants to name just a few By 2004 the unit shipments of such appliances will exceed those of the PC 12 Historic Perspective Technology discontinuities drive new computing paradigms and applications E g Xerox Alto 3Ms 1 mips 1 megapixel 1 mbps Fourth M 1 megabyte of memory From time sharing to client server with display intensive applications What will drive the next discontinuity What are the new metrics of system capability 13 What s Important Shifts in Technology Metrics Display human computer interface More ubiquitous I Os e g MEMS sensors actuators and modalities speech vision image How to Quantify Connectivity computer computer interface Not bandwidth but scaled ubiquity Million accesses wired and wireless per day Computing processing capacity Unbounded capacity utility functionality very high mean time to unavailable gracefully degraded capability acceptable 14 What s Important Shifts in User Applications Metrics Cost Human Effort Save time Reduce effort The Next Power Tools Leveraging other peoples effort expertise e g What did Dave read about disk prices e g What did people who buy this book also buy 15 Outline Scenario and Characteristics of Future Information Technology Embedded Systems Automotive Home Networks Smart Dusts Universal Radios
