摘要
针对红外图像采集系统中的PCI-E设备模块开发,重点介绍了其作为主设备时的工作情况及其优势。并介绍了基于WDF模型的PCI-E主设备模式的驱动开发过程。列举了测试结果,结果表明主设备方式CPU占用率更低,数据传输速率更高,并验证了驱动程序的稳定工作。
The development of the PCI-E module for infrared image acquisition system is described.Advantages of PCI-E device is described when working as master device,and introduced the PCI-E device driver development based on WDF.The testing results show that the master mode has lower CPU utilization and more efficient data transfer,and prove the driver works stably.
