看说明，支持POSIX接口，方便移植Linux第三方程序
另外，支持多核CPU，也就是说可以把多核A核SOC跑起来。

最后一个exception好像是说如果只是用它，引用头文件或者链接它生成可执行文件，不需要整个application也变成GPL。这个好呀，几乎就是可以商用闭源了，大不了只需要开源修改的RTEMS部分代码，应用代码不需要开源

作为特殊例外，包括文件中的RTEMS头文件，实例化RTEMS泛型或模板，或将其他文件与RTEMS对象链接以生成可执行应用程序，本身并不会导致生成的可执行应用程序被GNU通用公共许可证覆盖。但是，此异常不会使GNU Public License可能涵盖可执行文件的任何其他原因无效。
google自动翻译, 貌似应用代码不用开源.
