The Research of Embedded System in Industrial Control

The degree of automation of industrial control has been improved by the development of embedded systems.This paper conducts analysis and comparison of the VxWorks operating system RTLinux, and gives a preview of the development trend of industrial embedded systems finally, through the analysis of the characteristics of industrial control system and its special requirements for embedded software and hardware,which focus on the arm series processor,and.

A Dual-Core Operating System Framework Based on AutoSAR OS for HCS12X Series Processor

One kind of processors with coprocessor is widely used in control areas. Traditional single-core operating system (OS) cant support the coprocessor. In order to take full advantage of the performance of the processor, we presented a real-time operating system framework named AutoOSEK-CP on the basis of AutoOSEK, which is a single-core operating system based on AutoSAR OS, to support dual-core processor. In this architecture, alarm management, interrupt processing and inter-core communication mechanism were moved in coprocessor module, and the master processor was responsible for the other functions of OS. Finally, we designed a prototype of AutoOSEK-CP to test the performance in HCS12XEP100. The results showed that the real-time performance and the time-tick accuracy were improved significantly compared with AutoOSEK.
