中文摘要：

在流体系结构中,标量核同流处理核是异构核,它们之间的协同是流处理器能够正确、高效运转的基础.文中针对异构核间所采用的软件协同方法性能低的问题,提出了一种软件和硬件相结合的异构核协同方法,并基于MASA-I流处理SOPC系统进行了实现.使用媒体和数字信号处理领域核心算法进行测试的结果表明,与软件协同方法相比,使用文中方法的协同性能有2个量级的提升,程序整体性能提高一倍.

英文摘要：

In stream architecture,scalar core and stream core are heterogeneous cores,and achieving the cooperation between them is a significant basis on which the stream architecture can run correctly and efficiently.Aiming at solving the problem of low performance caused by software method,this paper presents a cooperative method in which software modules work with hardware logic,and implements it on the MASA-I stream processing SOPC system.Kernel algorithms of media processing and signal processing are used to evaluate this method.The results show that it is more advanced than the software method in that hardware/software method can achieve promotion of cooperation performance by two orders of magnitude and double the kernel performance.
