-## RT-Thread Smart 的架构
+# RT-Thread Smart 简介
 
 RT-Thread Smart 是基于 RT-Thread 操作系统上的混合操作系统，简称为 rt-smart，它把应用从内核中独立出来，形成独立的用户态应用程序，并具备独立的地址空间（32 位系统上是 4G 的独立地址空间）。
 
+## RT-Thread Smart 的架构
+
 以下是 rt-smart 的整体结构框图，在硬件平台的基础上通过 MMU、系统调用的方式把整个系统分成了内核态及用户态。

 RT-Thread Smart 的核心实现是 lwP，进程管理模块（ `rtthread-smart/kernel/components/lwp` ）。它包括了如下的几个部分：
