Linux 这样的类 UNIX 操作系统相比，一般意义上的传统嵌入式操作系统具有一些
特殊性。举例而言，诸如 uClinux、uC/OS-II、eCos 等操作系统，通常运行在没有 MMU（内存管理
单元，用于提供虚拟内存支持）的 CPU 上；这时，往往就没有进程的概念，而只有线程或者任务的
概念，这样，MiniGUI 的运行环境也就大相径庭。因此，为了适合不同的操作系统环境，我们可将
MiniGUI 配置成三种不同的运行模式：-UNIX-like Linux operating system compared to the general sense of the traditional embedded operating system with some specificity. For example, such as uClinux, uC/OS-II, eCos, such as operating systems, usually run in the absence of MMU (memory management unit, used to provide virtual memory support) on the CPU At this time, often there is no concept of process, and Only the concept of threads or tasks, so that, MiniGUI also different from the runtime environment. Therefore, in order to suit different operating system environment, we can be MiniGUI configured to run three different modes:
