The complexity of avionics system functions and the increasing scale of system software bring great challenges to the development, verification and update maintenance of the system. Based on the partitioned real-time multi-partition embedded operating system, establish reusable and extensible service components, design and implement service-oriented open software architecture is a solution to build the next generation of avionics system software that is being explored in the field of avionics technology. This paper analyzes the development trend of the existing avionics system software architecture and the key problems of realizing software component and function service. For the open architecture, designs the structure and service call mechanism of service registry. Then, aiming at the problem of service management in multiprocessor architecture, a scheduling strategy was designed to keep the consistency of service information of each processor. Finally, Based on the matrix653 operating system, the verification environment was built and the realization mechanism of service components was verified, which lays the foundation for the service management and service function realization under the real-time multi-partition embedded operating system.
