Extending the Von-Neumann Architecture and Moore’s Law The Computer in 2020 Extending the Von-Neumann Architecture and Moore’s Law

The Von-Neumann Architecture

Von-Neumann Bottle Neck Memory is 1 Dimensional Must right code to model data that is often 2 dimensional Keep floating point and integers separate index registers, indirect addressing, and virtual memory

Moore’s Law & Transistors 1971 2,250 1974 5,000 1985 275,000 1997 7,500,000 1999 24,000,000 2000 42,000,000 More even as we speak

Extending Moore’s Law Nanotechnology Nan 1 * 10 E-9 Greek word for “Midget” Placing atoms where we want them Atomic Force Microscopy Scanning Probe Microscope

Building Tomorrows Chips “one atom at a time” E-beam Etched Microchips on the nano scale 100 NM wide isolated lines 150 NM wide nested lines

Size Examples 100 NM = 0.0000001 meter 10 UM = 0.00001 meter Current Etched Size = 13 Microns E-beam lithography can yield 5NM
