漫谈CPU的品级。
（CPU-CN站长Henry原作，转载请注明出处）

   早期的CPU，一般很单纯的分为民用品以及军用品。从第二代CPU（8080）开始之后，CPU由于大量应用于不同的领域以及行业，逐渐产生了不同的品级。

  主要有如下4大类：

       民品（商用，民用），
      工业品(高端工业设备)，
      军品（军事领域），
      航品(航天)

     我们来看看最常见的一种--民品级CPU

      第一代的8位的民品级CPU

    上图的这只C8008，虽然是陶瓷金封，但也主要用民用。

此主题相关图片如下：


   上图这一只C8008就是最早提供与美国军方的产品，以M开头，M是（Military）的第一个字母。可以看出，早期的军品与民品的差别实在不大。

   下图这只是在板的军用MC8080A，作为藏品来说这是可遇而不可求的极品！

此主题相关图片如下：

   军品CPU至少要求有很高的可*性。要耐高低温冲击、过压过流冲击、加速度冲击等等。能做到3防（辐射，高温，腐蚀，生化？？）等等，所采用的军用标准俗称“军标”，如美国军队的CPU类芯片的军标是以“5962-”开头，军用标准可以保证在什么样环境下(比如失重,高压,高温,离子撞击等恶劣条件)多长时间的失效比率在多少，加上军队一般都是冤大头，有米，同样功能的芯片，  价格要高出N倍(N=5 到 500)。

  再看下面的民品386Ex，用简单塑料封装就可以应付民用需求了：  

此主题相关图片如下：


     对比一下军品386Ex , 好家伙！不仅用耐高温的陶瓷，容易散热的金顶，而且比普通的386都大上一整圈，我量了一下尺寸，与PGA封装的486一样大小，可见早期的军用CPU是一味的追求稳定，而不太注意体积的小型化）。

    当然，从价格上来看，民用386Ex是10-30元RMB一枚，这只军品新品报价是RMB 20，000，光一枚芯片就赶上现在一部中档服务器了。

  关于军品我再多一句嘴，凡是CPU收藏爱好U发现芯片上标了 5962-XXXXXXXX 标识的，一般可以断定它是一只美军军用芯片，如果JS因为不懂货而以民品的价格卖给你，那你就在一边偷着乐吧

  由于军品是战略物资，USA是绝对禁止出口的。虽目前IC市场上也可以看到军品的踪迹，是因为多数是拆机货（奇怪，一般USA的军品都是要严格销毁的。可能有漏网之鱼。）还有一些是80XX这类双列直插的芯片。

  因为军品的暴利，我见到过非常多的Remark的军品芯片，特别是看到一颗民品的386改装的军品，在普通的陶面上也印了5962-XXXXXXX 的军标，显得有点滑稽：）所以藏友们在购买这一类CPU时一定千万要当心。

接下来我们来讨论一下工业品，

工业品的要求虽然没有军品那么多限制，但耐高温也是必需的。比如，大家都知道，民品的386SX绝对是塑料封装的，如下图：

而工业品的386SX就没有那么简单了。

    TA80386SX可谓工业品CPU中的典范，主要应用于比较恶劣的工业级环境！价格也是一般民品的3到10倍。

      关于航品，也是最神秘的一种，我目前来说还没有亲眼目睹过，我曾多次在一些资料上查阅到相关介绍，比如美国在上世纪70年带发射的深空探测器旅行者系列飞船，就采用了航品的Intel 8085处理器。试想这些深空探测器要在太空中飞数十年，在高强度的宇宙射线以及接近于绝对零度的环境中工作，假如CPU死机，可没有人能够给他们去按复位按钮啊：）

此主题相关图片如下：

下表为一些卫星以及飞船使用的处理器：

MSTI-3	1750A, R-3000
Pluto Express	32 bit RISC
Sampex	80386, 80387
SMEX	80386, 80387
SWAS	80386, 80387
TRACE	80386, 80387
WIRE	80386, 80387
FUSE	80386, 80387, 68000
Surrey MicroSat	80386EX (2)
UoSat-12	80386EX (3)
FAST	8085 (2)
HealthSat-II	80c186 (2), 80c188
PoSat-1	80c186, TMS320C25, TMS320C30

    今天刚刚得到神六顺利返航的消息，非常振奋！我可以断言，我国神州系列飞船所搭载的设备中的处理器应该全部都是航品级的芯片。（是不是国产的则不得而知，因为中国的神州龙芯目前还不是特别成熟。）

很仔细的读完了LZ的文章  收益非浅呀，

看来虽然自己藏了很多U,但还是很菜地
