At the beginning of the ANC-100E AN-X2-AB-DHRIO handling process, the CPU did not turn on or off the interrupt receiving operation. As a result, on the Windows platform, there were no issues. When generating the PCIe IP core, the transmission bandwidth limit was set to 2Gbps. When testing various services on the 1G Ethernet port, it was stable and there were no operating system crashes; However, during VxWorks system testing, due to its excellent real-time performance and timely response to interrupts, the operating system may encounter another interrupt while ANC-100E AN-X2-AB-DHRIO an interrupt service program, directly causing the VxWorks system to crash, as shown in the following figure.

Of course, ANC-100E AN-X2-AB-DHRIO is also caused by the non-standard interrupt handling process. In the future, we will also add steps to enable switch interrupts in the Windows driver and test the minimum interval for corresponding PCIe interrupts in Windows. However, based on current test data, the speed of PCIe interrupts in Windows is definitely much slower than that in VxWorks.
