家园 【原创】从龙芯1千万芯片销售谈起

李国杰在给政协委员视察时说与ST签订协议,ST承诺年销售1000万片,这是李国杰显示知识创新工程的成果,否则对不起国家十五期间给科学院的几十亿人民币。与ST签的是战略协议,说是1000万片,又不先交钱,河内方家如果有兴趣熬到2007年底查查ST销售龙芯就会明白这是怎么一会事,不过想想粉碎四人帮后高呼到2000年实现四个现代化-->到2000年变成到2050年进入中等发达国家,李国杰吹的这个牛真悬,不要晚节不保。

至于性能每个都比前代超3倍,脸皮真厚,市场上又没见过这系列的东西,还不是由他说了算,但由于汉芯的丑闻,至少2E是比较严格测试的,选了几个超频能力比较强的,从默认的500MHZ超到1G,这就是所谓的达到P4的中档水平(2G),这是申请书提出的,当时鉴于汉芯的压力,科技部部长徐冠华亲临验收会会场,据说测试组公布指标后,科技部高新司的领导长长地嘘了一口气。这个指标一公布,后续的就不好办了,所以2E后面的在性能指标上只说比2E提高20-30%,比Intel现在代际产品的性能还不如。

本人对CPU的产业化不是十分熟悉,目前2E的产品定位比较尴尬,作嵌入式用,3-8瓦的功率明显太大,目前几款常用的嵌入式CPU远远小于1W,如果用龙芯2E,无论是手机类还是PMP类,手持是无望的。作通用CPU,只能用Linux,据说几年前科技部在强行推Linux,结果每一个司局设了一台Linux做做样子,大家平时工作还是在Windows下,不知现在科技部这批Linux机是否扔了。反正现在科技部网站上公布的课题指南之类都是Word格式。还有一个出路就是笔记本,它有一个先行者,VIA的Cyrix已经与同方合作提出3999元的笔记本,打的就是Cyrix的CPU功耗低,只有几瓦,但大家知道,笔记本的功耗,液晶屏,主板,硬盘等都是有较大功耗的,虽然笔记本功耗小对整体功耗及散热大有好处,但2E的性能无法与AMD与Intel的双核竞争,只能走低端路线,但低端的配件往往比高端产品耗能高,综合起来笔记本的电池持续能力强不了多少,所以同方的那款产品电池续航能力也只有3个小时。龙芯2E性能比不上VIA的C7-M,再加上又是Linux,到底有多少市场不好说。

说白了,中国政府支持一、二支队伍跟踪世界CPU先进水平,就象国内农业企业家一样,先抄,抄熟练了做自己的,从低端市场慢慢地切入,越做越大。现在是科学家忽悠企业家,企业家忽悠老百姓。我的影响中李国杰不是这样的人,难道遇到59岁难关了?

家园 要求太高

非得龙芯一上来就拳打intel,脚踢amd。

搞一款真能用的cpu,几十亿就不算个啥。

家园 你的确不了解CPU

大概你一位这个世界只有I和A两家作CPU吧。

用途别的不说,现在军用的也不过是486-586的级别。龙芯能保住着一块就已经够吃了。

另外你的比较方式很有意思阿。和性能差的就比功率,和功率大的就比性能。

家园 明显就是来故意唱衰龙芯的

一股冷嘲热讽的口气

最不喜欢这种没意思的文章,拜托,要打击国人信心也应该高明一点不是,这种文章没人愿意看的

400M主频的cpu性能不一定小于1G主频,体系不一样的cpu比较主频没什么意义,简单举个例子,PS2主机的主频也只不过300M hz,不过他的处理能力是奔腾300M hz的CPU能比的吗?就连现在P4的机器跑PS2的移植游戏性能都远远不如PS2呢

家园 龙芯是军用级设计么?

你莫非在开玩笑?

中国军方的军用级芯片主要靠走私美国货。可靠性主要靠工艺和封装保证,这是中国的弱项。

家园 简单比较主频的确不合适

拿来跑跑spec或者是sissoft benchmark 之类的性能测试软件就可以知道了。

龙芯靠3-8瓦功耗可以跑到早期p4得性能,这种话说出来恐怕是把大家当傻子忽悠呢。

家园 不懂这一句话有什么不对

和性能差的就比功率,和功率大的就比性能。

这句话很对啊。 现在的芯片发展本来就有两个方向:低功耗(笔记本、随身听等等)和高性能(工作站),算上工控、军品还有一个高可靠性。如果在两个方面都不突出,那说明在市场上的位置不好。

在wiki上说:

Godson

Godson

From Wikipedia, the free encyclopedia

This article is about a computer processor chip. For a male godchild, see godparent.

The Godson series, or "Dragon chip" for its origin, is an architecture of general CPUs developed at CAS (Chinese Academy of Sciences). The chief architect is Professor Weiwu Hu of ICT (Institute of Computing Technology). Type I (introduced in 2002) runs at 266 MHz, Type II is 64 bit and runs at 500 MHz (reportedly comparable in performance to the Pentium III). The Godson III is being targeted at 1 GHz, with multiple (8 to 16) cores. The instruction set is MIPS compatible, but the creators have backed away from promoting the chip as such due to threats of a lawsuit (see a Lexra history).

In September 2006, Li Guojie, director of the Institute of Computer Technology under the CAS announced a Longxin IIE (Godson IIE) a 64-bit chip containing 47m transistors and reaching 1GHz.

BLX IC Design Corporation, Ltd (BLX) (Beijing Longxin ?) was founded at 2002 by Institute of Computing Technology, China Academy of Sciences and Jiangsu Zhongyi Group. Based in Beijing, BLX focuses on designing advanced 32bit/64bit Godson general and embedded processor, developing software tools and reference platforms.

In March 2006 a €100 Godson II computer design called Longmeng (Dragon Dream) was announced.

In June 2006 at Computex'2006, Taipei YellowSheepRiver company has announced a Municator YSR-639, a mini-computer based on the 400MHz Godson 2.

[edit] Godson 2E

In the second half of the third quarter of 2006, China revealed the latest addition to the Godson series, the Godson 2E, which was already in early stage of manufacturing, and mass production was scheduled at the end of the year. According to developers, official tests showed that the Chinese chip can rival Intel Pentium 4 processor in performance and it was superior to the early series of the Pentium IV CPUs, but the Chinese CPU could be produced at a much lower cost.

Unlike processors from Intel, Advanced Micro Devices or Via Technologies, the Godson-2E is not based on the x86 instruction set. Instead, the chip uses a modified version of the MIPS instruction set that replaces proprietary instructions with ones developed by ICT. This means the Godson 2E cannot be used in PCs running Microsoft's Windows XP operating system, and thus the computing devices based on the Godson 2E would be most likely running the Linux operating system.

The processor runs at clock speed of 1 GHz and like other chips in the Godson family, the Godson 2E was designed by the Chinese Academy of Science's Institute of Computing Technology (ICT) and was the first Chinese CPU produced using 90-nanometer process technology. Earlier versions of the Godson 2 chip were produced using a 180-nanometer process and ran at clock speeds up to 500MHz. Godson 2E CPU contains 47 million transistors, more than the 40 million of the Pentium IV. But this processing power will not be a drain on laptop batteries, as power consumption is between 3 to 8 watts, according to academician Mr. Li Guojie (李国杰), director of the institute. Mr. Li Guojie (李国杰) also announced that at the end of 2006, scientists would start to upgrade Godson 2E to Godson 2F, which will improve performance by about 30% and power consumption reduced by about 50%. By 2008, Godson-3 is scheduled to enter production.

On November 13, 2006, at the [Chinese Academy of Science's Institute of Computing Technology (ICT), Mr. Li Guojie (李国杰) announced to the public that "Godson 2E is ready for mass production. Mr. Li Guojie (李国杰) told the public that from Godson 1 to Godson 2B, the capability of the chip has tripled, and from Godson 2B to Godson 2C, from Godson 2C to Godson 2E, the capability has continuously tripled. On the average, the capability of Godson series chip doubles every year, four times of what Moore's law claims, and China should accumulate small successes into large success."

另外,如果现在ST承诺销售1000万片,为什么在ST网站搜索"godson"没有结果? BLX网站上也没有龙芯2相关资料和开发工具包。

神州龙芯 > 下载中心

除非这1000万片只被几个用户包了,否则现在应该有样片、开发工具包等等可以定购、下载,否则下游厂家怎么拿得出产品?我们这里的芯片从下家拿到样品,到下家拿出系统-〉下单-〉大规模生产,至少半年(极顺利情形,一般要一年甚至更多)。而没有下家的订单,怎么敢大规模生产?

我的判断是:这里肯定有不小的夸大。

家园 军芯的开发在西安那边

龙芯吹的比做的多……外围电路的优化还差的远,这个才是最比拼功力和经验的……军版486到现在还是禁止向前共产国家出口的……TG全靠走私……

家园 跟意法只是一个意向性协议而已,说不好听的就是

人家在你需要的时候送你个面子而已。

国杰也院士了,也没什么可追求的了,所长不当了待遇还是有的。

做芯片的,号称有产品而不提供datasheet下载的,统统都是扯蛋。近的如龙芯、远的有号称WLAN/WCDMA芯片通吃的六合万通。这一点搞过开发的都明白。

家园 花一个!当初有人在西西河替陈进辩护,

俺让他把DATASHEET给大家看看,如何要样片,那伙计就不做声了.

后来的故事大家都知道了.

家园 陈进跑到哪里去了?

大摇大摆回美国了?怎么一点惩罚都没有,不成为科技骗子的天堂才怪。

家园 如果陈进以诈骗罪论处,有人要判渎职
家园 中科院计算所的都笑了。

现在是科学家忽悠企业家,企业家忽悠老百姓。李国杰不是这样的人,

中科院计算所的都笑了。

家园 都揪出来那么久了,还是没人承担

这就是我在另一条讨论里面所说的给科研创造客观条件,在国外要是那么高调的欺骗,一早有一干人等要承担后果,你敢去这样骗美国国防经费看看。

这种客观条件下要出好的科学家科研成果,天上掉馅饼。

家园 不知道上海这次动作能否带出一些东西出来
