Linux系统下PCIE to RapidIO桥驱动设计与实现

Driver design and implementation of PCIE to RapidIO bridge under Linux operating system

为了使X86架构的CPU能通过PCIE总线连接到Rapid IO系统中,利用PCIE to Rapid IO桥芯片Tsi721的硬件特性,在Linux操作系统下开发该芯片的驱动程序,实现了PCIE总线网络和Rapid IO总线网络的无缝对接。通过实际测试,验证了工作的正确性,并将此应用于某型号二次雷达显控终端中。

In order to make the CPU with X86 architecture connect to the Rapid IO system through the PCIE bus,by using the hardware features of the PCIE to Rapid IO bridge chip Tsi721,the chip driver is developed under the Linux operating system,realizing the seamless connection between the PCIE bus network and the Rapid IO bus network. Finally,the actual test verifies the correctness of the method,and the diver is successfully applied to the display and control terminal of a secondary surveillance radar.
