摘　　要：RT-Thread Smart采用微内核的设计思想,将操作系统自身的服务组件从内核中剥离出来,在用户态以进程的形式运行,避免服务组件的错误造成内核崩溃,提高系统整体的稳定性和可靠性。另一方面,依据用户配置选项,RT-Thread Smart继续支持将组件编译进内核中,以获得更佳的性能和向下兼容性。为了支持这些特性,RT-Thread Smart实现了对MMU和进程管理的支持,并通过通道机制来完成内核和用户态进程间的数据交换。Designed with the microkernel principle,the service components of rt-smart are separated from the kernel and run as processes in the user mode,which makes the kernel immune to the runtime errors occurring in the services.In the way,the whole system becomes stable and robust.On the other hand,according to the configuration options selected by users,these service components are still permitted to be compiled into the kernel in rt-smart,in order to get better performance and backward compatibility.To support these features,rt-smart takes advantage of the support of MMU and process management,completes the data exchange between the kernel and user-mode processes through the channel mechanism.
