RTOS for SoC embedded control applications

Due to the importance and increasing complexity of electric control applications, the demands on Real Time (RT) platforms for such systems increase every year, which motivates moving these applications onto high performance System on Chip (SoC). Furthermore, an efficient handling of an embedded Real Time Operating System (RTOS), could accelerate the various software control tasks. Our claim consists of implementing a RT motor control drive in SoC. This paper deals with the different approaches used for an efficient implementation of such system leading to their successful completion with a good precision and a real time execution. The following pages outline the electric control applications constraints, present the new trends on embedded digital control systems with comparing different control implementation solutions and investigate the gain with using embedded RTOS-kernel for control task management. The implementation results validate successfully the benefits of using RTOS for embedded control applications and show that the SoC implementation on hard-core processor provides interesting control performance.
