HR-TECS: Component technology for embedded systems with memory protection

A software partitioning has been used to develop safety-critical systems in recent years. In addition, software component technologies supporting a software partitioning have been developed. This paper describes the new component technology for embedded software that requires memory protection, which is one of the important features for the partitioning. HR-TECS is a new component technology based on the real-time operating system supporting the static memory layout. Developers can easily allocate components to partitions in order to protect memory areas. In addition, HR-TECS supports inter-partition communications so that developers can implement components without consideration for inter-partition communications. The results of evaluation demonstrate the effectiveness of HR-TECS.
