FCOS: A Partitioned Operating System towards the Integrated Modular Avionics
To decrease the weight, size, cost and energy consumption of the avionics, the Integrated ModularAvionics require that the operating system should integrate the traditional systems with different critical level and run-time attributes into one platform. Therefore in the paper we propose a strongly partitioned operating system model which can guarantee the every partition was completely independent and isolated within this model A fault in one partition would only affect the partition itself rather than other partitions. And then the strongly partitioned operating system kernel FCOS is discussed in detail, including the system architecture, partition scheduling, task model, inter-partition communication and memory management Besides, we analyzed and evaluated the kernel FCOS base on different benchmark, and optimized the memory management. At the end of this paper we provided the application of FCOS in a weapon system on which the traditional three systems are integrated into one platform.
