CPU是计算机的核心部件，是执行程序指令，完成各种运算和控制功能的大规模集成芯片。随着科技的进步，CPU的发展非常迅速，个人计算机从8088(XT)发展到现在的pentium4时代，只经过了20多年的时间。CPU发展到今天，Intel和AMD两个大公司都相继推出了64位微处理器，从CPU的发展趋势来看，它们都淡出了发展高频率CPU的领域，而从功能和应用范围提高处理器的性能。高性能、低能耗、高速度、低成本是CPU厂家和消费者一直追求的方向。

要篇英文译文，谢谢了！

CPU is the essential part of the computer .It is a large-scale intensified chipset that deals with commands processing and various works of calculating or controlling. With the development of science and technology the increase of CPU industry is in a threatening pace. As we can see, in a little more than 20 years the personal desktop (or Personal Computer) had been developed from the Mode.8088 (xt) to Pentium4.Up to now, the two major CPU manufacturers INTEL and AMD had released their 64bit processors in succession. On the long run, we can see from the trend that both two manufactures have ceased to develop a higher frequency CPU.however they sought to enhance the performance of processors in the area of function and application. The goal of seeking for higher performance, power saving and high-speed low-cost device is the everlasting direction not only for the CPU manufacturers but for the customs as well.
