  • 简介:现在,内部任务的干扰是在分析multicores的预定行为的主要困难。预定可预言的嵌入的multicore体系结构MERASA,它允许安全最坏的执行时间(WCET)评价,作为一个吸引人的解决方案出现了。在建筑学,WCET能被能被干扰知道的公共汽车仲裁人(IABA)和划分例如columnization或bankization的动态缓存围住的上面的界限延期(UBD)估计。然而,这体系结构面对在减少的UBD和有效分享的缓存利用之间的窘境。获得更紧密的WCET评价,我们建议由优化与IABA和二水平的划分缓存在multicore系统上印射的bank-to-core减少UBD的一条新奇途径。为这,我们首先基于内部任务的干扰延期的分析介绍一个新UBD计算模型,然后提出bank-to-core与最小的UBD印射和优化算法的核心顺序优化方法。试验性的结果证明我们的途径能从4%~37%减少WCET。
