Research on Clock Synchronization Method Based on Partition Operating System and TTE
With the continuous improvement of the integrated and modular level of avionics systems,the increasing software functions have led to an increase in the scale and complexity of the system.In order to meet the high safety and reliability performance requirements of the system,ensure the periodic tasks timely execution,this paper proposes a clock synchtonization optimization algorithm based on TTE and ARINC 653 partition OS.On the basis of the traditional algorithm,the algorithm optimization is carried out for the two stages of start-up synchtonization and periodic adjustment.The experimental results show that the algorithm synchronize the clock period of network and OS more precise,shoten the start-up synchton-ization time and improve the presicion of periodic adjustment.
