章节摘录

　　Multi-Core Processing　　In 1965， when he first set out what we now call Moores Law， Gordon Moore （who laterco-founded Intel Corp.） said the number of components that could be packed onto an integratedcircuit would double every year or so （later amended to 18 months）.　 In 1971， Intels 4004 CPU had 2，300 transistors. In 1982， the 80286 debuted with 134，000transistors. Now， run-of-the-mill CPUs count upward of 200 million transistors， and Intel isscheduled to release a processor with 1.7 billion transistors for later this year.　　For years， such progress in CPUs was clearly predictable： successive generations of semiconductortechnology gave us bigger， more powerful processors on ever-thinner silicon substrates operating atincreasing clock speeds. These smaller， faster transistors use less electricity， too.　　But theres a catch. It turns out that as operating voltages get lower， a significant amount ofelectricity simply leaks away and ends up generating excessive heat， requiring much more attentionto processor cooling and limiting the potential speed advance——think of this as a thermal barrier.　 To break through that barrier， processor makers are adopting a new strategy， packing two or morecomplete， independent processor cores， or CPUs， onto a single chip. This multi-core processor plugsdirectly into a single socket on the motherboard， and the operating system sees each of the executioncores as a discrete logical processor that is independently controllable. Having two separate CPUsallows each one to run somewhat slower， and thus cooler， and still improve overall throughput forthe machine in most cases.　 From one perspective， this is merely an extension of the design thinking that has for several yearsgiven us n-way servers using two or more standard CPUs; were simply making the packagingsmaller and the integration more complete. In practice， however， this multi-core strategy represents amajor shift in processor architecture that will quickly pervade the computing industry. Having twoCPUs on the same chip rather than plugged into two separate sockets greatly speeds communicationbetween them and cuts waiting time.　 The first multi-core CPU from Intel is already on the market. By the end of 2006， Intel expectsmulti-core processors to make up 40% of new desktops， 70% of mobile CPUs and a whopping 85%of all server processors that it ships. Intel has said that all of its future CPU designs will bemulti-core. Intels major competitors——including Advanced Micro Devices Inc.， Sun MicrosystemsInc. and IBM——each appear to be betting the farm on multi-core processors.
