Abstract :
This article introduces the background of the design and a unique idea of PCI interface circuit at first. The circuit mainly focuses on the Linux-based driver by introducing interrupt. Then the paper describes the compilation and installation of driver and interruptions which include requesting, handling, and releasing. At the same time, the application of PCI interrupt in data acquisition card is also presented. Finally, result shows that reading PCI bus data in interrupt mode can increase the efficiency of data acquisition in comparison with the inquiry mode.
