摘要
为解决当前重演技术采用视频录取/重放模式在嵌入式系统应用中存在的问题,提出了在VxWorks操作系统下,应用多任务机制实现系统工作过程事后重演的一种数据重演解决方案,具有不需增加辅助设备、可以实现选取时段任意次进行重演等特点,对深化系统层面的重演技术研究具有借鉴意义。
To solve the current existed problems in the replay technology by use of recording/playback mode in the embedded system,a kind of data replaying solution was put forward to apply the multi-task mechanism to realize the replay of the system working progress in VxWorks operating system.Without adding auxiliary equipment,this method is capable to select any period of time to replay at any random number of times.The method has referential significance for the replay of deepening system level.
