jslinux：用JavaScript写出一个PC模拟器，上面运行Linux
1、主页面 (http://bellard.org/jslinux/) 很简单，主要调用了 如下两个 js 文件。
http://bellard.org/jslinux/term.js
http://bellard.org/jslinux/cpux86.js
2、term.js 里也没有发现什么特殊的地方；
3、cpux86.js 使用到一个 load_binary 的函数，查看了一下实现，是通过 XMLHttpRequest 来取如下三个 bin 文件：
http://bellard.org/jslinux/vmlinux26.bin
http://bellard.org/jslinux/root.bin
http://bellard.org/jslinux/linuxstart.bin
通过迅雷来看，这三个文件，总大小 3.6M 以上。因为网站在国外，很卡。
通过代理下载成功。在本地试了一下，不错。

The code is written in pure Javascript using Typed Arrays which are available in recent browsers. It was tested with Firefox 4 and Google Chrome 11 on Linux, Window and Mac (it does not work with Chrome 12 beta. As far as I know, it is a bug in the browser). In any case, a fast Javascript engine is needed to have good performance.
Typed Arrays 就是用于操作二进制文件的。

Abstract
This specification provides an API for interoperability with native binary data. It defines a generic fixed-length buffer type, as well as accessor types that allow access to the data stored within the buffer.
The functionality described here originated in the WebGL specification [WEBGL].
