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。

不清楚 到底 通过js怎么操作二进制文件。
代码又不能读。
博主清楚吗?

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].
