【摘要】 中断延迟是评估嵌入式操作系统实时性能的重要指标.本文利用Windows CE.NET中的ILTiming进行中断延迟测量,并分析了造成中断延迟的原因,同时也提供了测试Windows CE.NET中断延迟的方法.实验结果表明,实时性能与CPU频率及系统负荷成反比关系.更多还原

【Abstract】 Interrupt latency is the key metric assessing the real-time performance of Windows CE.NET.This paper measures the interrupt latency of Windows CE.NET by ILTiming,then analyses the reason causing interrupt latency,and also presents the methods to measure interrupt latency of Windows CE.NET.The experiment resaults show that the real-time performance is opposite to CPU frequency and system payload.更多还原
