| Abstract: | The real-time performance is an important part when evaluating embedded systems.Interrupt latency is the key metric assessing the real-time performance of embedded systems. This paper measures the interrupt latency of WinCE 4.2 and 5.0 by ILTiming , then analyses the reasons causing interrupt latency , and also presents the methods to measure interrupt latency of WindowsCE for PXA255 processor BSP. |
