PC-based Control, Software and Bus Trendshaving trouble. This software will work when you need it as a personalslave in the computer and allow easy collaboration over the Internet.The PC now handles many tasks that once were the sole provinceof large computers. The PC of the future will have terabytes of storage.Displays may be flexible and you may unfold them from your pocketlikecell phone. Voice recognition may not completely replace mice becauseof privacy concerns.You will need lots of connections and they will be in the walls andthe floor. What may go away is those wires to the phones, the keyboardand the mouse. These may all go wireless.PCs should be more reliable and customizable. They will need tofree us from maintenance hassles, compatibility glitches and an everspiralingrate of obsolescence.The technology should provide advances in processors, storage,displays, and all the supporting technologies needed to make the PCmore useful.Processing PowerThe innovation for the years ahead in silicon fabrication and CPUarchitectures will produce a billion transistors on a chip by 2011 orsooner and computing devices will be much more powerful. Intel’sPentiums and AMD’s faster K6 chips are tuned to handle graphics better.Intel founder, Gordon Moore, predicted that processing powerwould double every 24 months. Intel’s Pentium II has 7.5 million transistors.As the trend continues, Intel processors should contain 50 millionto 100 million transistors by the first decade of the 21st century (seeTable 5-3).In 1965, Intel Corporation cofounder Gordon Moore predicted thatthe density of transistors in an integrated circuit would double everyyear. His observation was called Moore’s Law and was later changed toevery 18 months. Moore’s Law has been relatively accurate for over 30years. Transistor density as well as microprocessor performance tends tofollow Moore’s Law. The cost of memory also continues to plummet (seeTable 5-4).In 1996 Intel predicted that by 2011, they would have a microprocessorwith 1 billion transistors which runs at 10-GHz. This would bedone using 0.07-micron semiconductor processing technology. The chip©2001 by The Fairmont Press, Inc. All rights reserved.
