Unformatted text preview: Moore’s Law Process attributes improvement Click to edit Master subtitle style of computing S. M. Ng, HKUST 11 Moore’s Law • Moore's law states: The number of transistors that can be fabricated on a very large-scale integrated (VLSI) chip doubles every two years. Figure 1: Moore's law for memory chips and microprocessors plotted on a semi-logarithmic scale, which has the effect of making nonlinear exponential curves appear linear. The uppermost purple curve is the Moore projection based on data up to 1975; note the kink correction around 1980, which shows that the so-called law is only an approximation.

Ng, HKUST 22 Moore’s Laws • • • • Computing performance per unit cost (halved every 24 months) The increase in hard disc drive capacity is similar to the transistor count (Kryder’s law) Pixel per dollar – in digital camera (B. Hendy) … S. M. Ng, HKUST 33 Transistors packed in a processor 1971-2004 (Intel Museum) S. M. Ng, HKUST 44 The price of a transistor (Intel Museum) The price per transistor on a chip has dropped dramatically since Intel was founded in 1968. Some people estimate that the price of a transistor is now about the same as that of one printed newspaper character. Copyright © 2005 Intel Corporation. All rights reserved. S. M. Ng, HKUST 55 The time of a process: on-off (Intel Museum) Because electricity travels a shorter distance in a smaller transistor, smaller transistors mean faster chips. It would take you about 25,000 years to turn a light switch on and off 1.5 trillion times, but Intel has developed transistors that can switch on and off that many times each second.
