一种有效监控及过滤1394总线消息的设计实现
Design and Implementation of an Effective Monitor and Filter 1394 Bus Message
摘要
Abstract
With the IEEE-1394b successfully applied in aviation field,bus monitor node need to extract the key data related to flight safe-ty from all the bus information,and then submit to the upper layer software for real-time processing. To meet the requirements,the key point is to check if the message ID which is extracted from monitor message matches the expected value. But expected monitoring infor-mation is thousands of varieties,for example,the traditional method checks the matching using CAM table,which takes a great deal of hardware resources. In this paper,put forward a method of multi-team search for specific messages. Experimental results show that the method can filter and monitor specific 1394 message in the cost of less hardware resources.关键词
