Porting RT-Thread to Cortex-M3 Processor

Abstract:

Based on the analysis of the characteristics of the RT-Thread and Cortex-M3, show the superiority of the combination of the two. On the study of RT-Thread and Cortex-M3 system structure and characteristics, RT-Thread is ported to the Cortex-M3 Skillfully. The PendSV exception of Cortex-M3 which can automatic saves part of the registers is used in the process of context switching to reduce the time of thread context switching, and improve the real-time property. This can be as a state-of-the-art design architecture used in intelligent instrument. The system is stable in the practical test, and possessed of popularization and application value.
