Today’s Chips: Moore’s Law

Gordon Moore, 1965
Number of transistor
per square inch doubles
approximately every18 months
üCost per device halves every 18 months
üMore transistors on the same area, more complex and powerful chips
üFuture chips are very hard to design!!!
üFabrication cost is becoming prohibitive



üEncoded by two voltage levels
ü +1.5 V 1  ,  0 V 0


üBoolean Algebra:
üVariables can take
Digital Representation of Logic Functions

values 0 or 1 (true or false)

üOperators on variables:
üa AND b                     a·b
üa OR b                       a+b         
üNOT  b                        b
