对CPU现状及发展趋势的分析The analysis of present situation anddevelopment trend of CPU摘要：现在CPU处理器的发展真可谓日新月异，着重介绍中国的龙芯及国际的双核技术，并介绍其未来的发展趋势，在此基础上提出了一些新的看法。
Abstract: now is the development of the CPU processor, changing the godson focuses on China and international dual core technology, and introduces its future development trend, based on this, advances some new opinions. 关键词：CPU，网络，双核技术Keywords: CPU, network, dual-core technology一、引言introduction随着网络时代的到来，网络通信、信息安全和信息家电产品将越来越普及，而CPU正是所有这些信息产品中必不可少的部件。
CPU的英文全称是Central Processing Unit，我们翻译成中文也就是中央处理器。
CPU（微型机系统）从雏形出现到发展壮大的今天，由于制造技术的越来越先进，在其中所集成的电子元件也越来越多，上万个，甚至是上百万个微型的晶体管构成了CPU的内部结构。
CPU的内部结构可分为控制单元，逻辑单元和存储单元三大部分。
With the advent of the era of network, network communications, information security and information appliances will become more and more popular, and the CPU is the indispensable part in all of these information products. The CPU's English full name is the Central Processing Unit, we translated into Chinese, that is, the Central processor. CPU (single-chip system) emerged from prototype to develop today, due to the more and more advanced manufacturing technology, in the integration of electronic components more and more, thousands, even millions of tiny transistors constitutes the internal structure of the CPU. Internal structure can be divided into the control unit of the CPU, a logic unit and storage unit three parts.二、中国CPU现状及发展趋势9月13日，中科院计算技术研究所承担的国家“863”项目“龙芯2号增强型处理器芯片设计”(即龙芯2E)正式通过了“863”专家组的验收。
该通用CPU已经达到了奔腾4的水平，这标志着我国在通用CPU设计和生产方面，取得了巨大的进展。
经专家鉴定，龙芯2号居国内通用CPU研制领先水平。
China's present situation and development trend of CPU on September 13, the Chinese academy of sciences institute of computing technology of national "863" project "the godson 2 enhanced processor chip design" (i.e. the godson 2 e) officially passed the acceptance of the "863" panel. The general has reached the pentium 4 CPU, this marked the our country in terms of general CPU design and production, has made great progress. Through/ /expert testimony, the godson 2 general CPU development leading level in China.与此同时，中科院计算所也宣布了进一步的研发计划，即会在2008年左右推出龙芯3号芯片，用于将来的服务器市场。
根据中科院计算所公布的产品路线图，龙芯3号将会是64位16核的芯片，而到现在为止的龙芯1号和龙芯2号系列芯片都是单核(龙芯1号是32位，龙芯2号系列为64位)。
之所以龙芯3号会跳过双核、4核、8核，直接进入到16核的设计，首先是因为计算所已经具备了设计16核芯片的能力，其次是实现跨越式发展的需要。
At the same time, ict also announced plans for further research and development of Chinese academy of sciences, which will be around 2008 to launch the godson 3 chips, used in the server market in the future. According to the calculation of the Chinese academy of sciences published product roadmap, the godson 3 will be 64 16 core chip, and so far the godson 1 and the godson 2 series chips are single-core (godson is 32-bit, 1 the godson 2 series for 64 - bit). Is the godson 3 will skip dual-core, 4, 8, directly into the nuclear design, first, because calculations have 16 nuclear chip design ability, the second is to realize the leap-forward development.据中科院计算所介绍，“十一五”计划期间，中科院计算所将研制多核的龙芯3号，可用来研制生产高性能的计算机和服务器，进一步缩小与国外先进水平的差距。
现在龙芯系列研发和推广的重点依然是龙芯2号产品，但与此同时也末放弃龙芯1号和3号的继续研发，龙芯家族的各号产品嵌入式系统(龙芯1号)、PC 机(龙芯2号)和服务器(龙芯3号)研发将齐头并进。
面对中国这个潜力广阔的大市场，龙芯还有很长的一段路要走，合理地找准市场地位，如何发挥其产品的技术优势并加大应用推广的力度，是目前龙芯处理所需要做的。
According to calculation of the Chinese academy of sciences, the "11th five-year" plan period, Chinese academy of sciences calculations will develop more nuclear the godson 3, can be used for the development and production of high-performance computers and servers, further narrowing the gap with foreign advanced level. The godson now the focus of the research and development and promotion is still the godson 2 series products, but at the same time also give up at the end of the godson 1 and 3 to continue research and development, the loongson family each number product embedded systems (godson 1), PC (the godson 2) and server (the godson 3) research and development will go hand in hand. In the face of China's vast market potential, the loongson or dragon chip has a long way to go, right market position reasonably, how to play the technical advantages of its products and stepping up its application popularization, is the loongson or dragon chip processing need to do.三、国际CPU现状及发展趋势international status and development trend of CPU两家世界上最大的处理器制造厂AMD和Intel曾都遇到一个难题，那就是“频/率”。
频率作为衡量处理器好坏的标准已经成为了大多数人的定论。
低频率就代表着一颗处理器性能的滞后，而如今不管是Intel还是AMD都同时遇到了“频率”这个难题。
在设计者提高处理器内部进程的数量、增加缓存容量等方法纷纷用尽以后，似乎残酷的现实告诉设计者们:单核心处理器已经走到尽头。
