Abstract: This paper introduces the model of communication between multi-task based on VxWorks RTOS. The model is based on UDP transmit mode and the concept of virtual device. It overcomes the defects of the old communication theory and can satisfy the real-time performance and system resource requisition of the RTOS. It analyses the principle, possibility and superiority of the model. Specific implementation is show in the end of the paper.
