CortOS is an Embedded RTOS
1. It is a free and open
2. Task switch is very fast
3. Interrupt service routine uses a separate stack
4. Calculate running time of Task
5. Device application interface (DAI)
6. It is a real-time multitask kernel which accords with CMSIS ( Cortex Microcontroller Software Interface Standard ).
7. <Atmega328> <ARM Cortex-M0> <ARM Cortex-M3> <ARM Cortex-M4 with FPU> <STM8>
8. Platform:
<1> STM8S-Discovery
<2> STM32F4-Discovery
<3> NuTiny-SDK-M058SSAN V2.1
<4> STM32F103R
<5> ATMEGA328

已经在M058上成功移植，支持中断嵌套，移植了非阻塞的串口驱动。
