摘要
为实现SOPC子系统与主机的相互通信,介绍了基于嵌入PowerPC的Xilinx FPGA的SOPC设计,使用Xilinx提供的OPB-PCI总线桥接器,完成了SOPC系统与其它PCI主、从设备的PCI通信接口。仿真、测试结果表明,该桥接器能以较高的传输效率实现PCI总线上各个设备之间的相互访问。该设计方法简单、快捷,可以很方便地实现SOPC系统的片上数据传输和处理,使SOPC硬件平台具有了优良的可扩展性能。
For communication between host and SOPC subsystem, introduce an SOPC design embedded with PowerPC based on Xilinx FPGA, which use an OPB- PCI host bridge to achieve the intercommunication between SOPC and other PCI peripherals. The simulation and testing result indicate that the host bridge can implement the communication among PCI device at a high efficiency, which is the simple and swift design method, can transmit conveniently the data processed at SOPC, making the SOPC hardware platform with an excellent improvable performance.
