Abstract
Message driving mechanism in two-level scheduling embedded system is analyzed.A new data structure for message is given,then designed task message queue and sub-task message queue which are made up of different messages and completely independent.The two queues can transfer messages in the way of zero-copy.Finally,it briefly introduced the operations and data structure of the message queue and how to driver task or subtask.
