摘　　要：提出了一种基于多任务管理系统的高清视频处理技术,具有提升高清视频处理实时性,优化计算资源利用率,降低高清视频处理应用设计难度的特点;首先,介绍了面向异构多核计算环境的多任务管理系统,用于多种类型任务的调度执行及计算资源的负载均衡;在此基础上,设计了一种软件流水线,将对于高清视频的复杂而重复的处理过程分解成多类型的任务,提交至多任务管理系统;最后,对基于多任务管理系统的高清视频处理技术进行了实验验证;结果表明,异构多核环境下,高清视频处理的计算性能提升了3.7倍。A method of high definition video processing based on multitask management system is presented, which has the features of improving the real--time performance of high definition video processing, optimizing computing resource utilization rate and reducing the de- sign difficulty of the high definition video processing. At the beginning, a kind of multitask management system based on the heterogeneous multicore computing environment is introduced, which is able to schedule and manage tasks and the loads of the computing resource. Based on this, the software pipeline is designed out to decompose the complex and repetitive video processing into several multi--type tasks, which will be submitted to the multitask management system later. Eventually, an experiment was carried out to test the technology of high defini- tion video processing based on multitask management system. The result indicates that, the computing performance of high definition video processing could be improved twice as much in the heterogeneous multicore computing environment.
