OverviewOverviewFrom Industrial Age to Internet Age
Industrial Age – Power abundanceInformation Age – Transistor abundanceInternet Age
New design imperative: From wasting watts and transistors towasting bandwidth and saving watts
The Microprocessor for the Internet Age - CrusoeIntegration, efficiency, compatibility, flexibilityMaximize energy efficiency!
Crusoe ApplicationsAnytime, Anywhere Internet computing (“waste bandwidth”)High-density computing servers (“save watts and transistors”)

Bandwidth: Scarce AbundantDramatic Bandwidth Acceleration in the 21st CenturyBandwidth: Scarce Abundant
Dramatic Bandwidth Acceleration in the 21st Century
Bandwidth growth is now outpacing Moore's Law by a factor of 10 Bandwidth will substitute for transistorsNew computing paradigm will be based on the runaway expansion of bandwidth (land and air)

The Internet AgeBandwidth Abundance Drives Digital Convergence
Key Technology Driving FactorsPower constraints (wireless Internet access)Transistor constraints (power/heat density)Abundant bandwidth (“fiber”-sphere and 3G/UMTS wireless)
The Emerging Paradigm: Digital ConvergenceMoving beyond the PC stage of computing:
General purpose PCs and consumer electronics converge into network-oriented smart devices with corresponding new servicesService delivery bundled with Internet access (DSL)The rise of “calm computing” (computers retreat into background)Microprocessors become adaptable peripherals
Key properties of emerging microprocessors (and devices):Integration, efficiency, compatibility, flexibility!

• “Morphs” PC into VLIW Engine Translates x86 instructions into optimized VLIW molecules
• Learns and improves with time • Can evolve to new devices,
usage models and content types
• 128-bit Very Long Instruction Word (VLIW) processor

SummarySummaryPast century - Microcosm
Abundant power and transistors, scarce bandwidthThe centrifugal law of the Microcosm
General-purpose computers migrate to network periphery (PC’s)“Home electric motor” stage of computing
Next century - NetsphereAbundant bandwidth
Anytime, Anywhere Internet connectivity, and rise of calm computingNew fortunes in ever-changing transmutations of multimedia and wireless computing devices will dwarf yields of cable and cellular
People relate to things, not electric motors or PC’s!
