面向RSoC的过程级动态软硬件划分

Dynamic hardware/software partitioning in function level for RSoC

软硬件划分作为可重构片上系统设计的重要技术手段,其结果直接影响到系统的性能。目前的软硬件划分大多只考虑从算法本身提高划分效果,忽略了划分结果的具体配置实现,导致划分效果很不理想。分析了预配置模型下的任务描述,给出了预配置调度优先级的计算方法,设计了一种预配置调度策略;针对软硬件划分与动态可重构的特点,提出并实现了一种结合预配置的软硬件划分算法,给出了一种评价软硬件划分方案优劣的方法。实验结果表明,该划分方法具有良好的划分效果。

As a key approach in reconfiguration system-on-chip（RSoC）,hardware/software partitioning impacts on system performance definitely.But most of the research on improving partitioning focus on the algorithm itself,and their neglecting in implementation results in poor partitioning.The features of partitioning and dynamic reconfiguration are presented.Then a partitioning method with pre-configuration is proposed,which makes task decomposition in pre-configuration model,and the priority for preconfiguration of the task is computed.At the same time,an evaluation function is designed to do assessment of the partitioning.Experimental results indicate that the method improves partitioning performance efficiently.
