The real-time and 12 * embedded characters are the most significant advantages of RT-Thread. 13 * 14 * - Real-Time Character 15 * 16 * RT-Thread has a real-time operating system kernel, with fully preempted 17 * multi-thread scheduler, inter-thread communication with timing sensitivity 18 * and transparent interrupt handling. 19 * 20 * - Embedded Character 21 * 22 * RT-Thread is suitable for embedded systems for small footprint characters. 23 * The kernel is implemented as a simple C library. The simplest application 24 * costs less than 1 Kbytes RAM on the ARM Cortex-M platform. 25 * 26 * @section kernel_arch RT-Thread Architecture 27 * 28 * RT-Thread system architecture is like: 29 * @image html System_Arch.png "Figure 1: RT-Thread Architecture" 30 * 31 * @section kernel_service Kernel API 32 * 33 * The Kernel APIs are the core APIs of RT-Thread, which supports the following 34 * features: 35 * - Multi-thread management and scheduler 36 * - Synchronization mechanisms, semaphore, recursive mutex and event set 37 * - Inter-thread communication, mailbox and message queue 38 * - Memory management, memory pool and dynamic heap memory management 39 * - Asynchronous timer 40 * 41 * For more details, please refer to @ref Kernel 42 * 43 * @section system_init System Initialization 44 * 45 * Once RT-Thread operating system starts up, the facility in system must be initialized 46 * firstly. 47 * 48 * For more details, please refer to @ref SystemInit 49 */ 50
