顺便说一句，那些指令非常简单：,他们从记忆存储器中,取出两个位置的结果，在倍增器中运行，一小部分电路，再将它们插回存储器中的某些地方去。

OK. All right, let me show you one other tool that I want to use. Which is, I've written that piece of code, I ought to check it. Well, I could just run it, but another useful thing to do is, I'm, especially as I want to debug these things, is to simulate that code.

好，那么，让我给大家讲下,我想用的另外一个工具吧,也就是，我已经写好了这一块代码，我应该去检查检查,那么我可以去运行它,但是特别是当我想要调试代码的时候。
