关于手工布线的问题,Intel的架构师是这么说的:
All of the analog circuitry, arrays, and performance-sensitive parts are definitely hand-drawn (schematics) and hand laid out. We're one of the few places that actually still do this (apparently Apple does too). You can tell which parts were laid out by hand if you look at die photos.
言下之意就是模拟电路和比较关键的地方手工布线。
关于是否全CPU手动布线的问题,我认为跟问大型软件公司是不是完全靠自己人手写代码的性质一样,关键的地方肯定有自己写自己调优,但若对每一行代码都拿出这种精力去关注,根本不可能,肯定有用到别处的一些代码模块插进来,开发糙快猛,诸如此类。 |
