Design and Implementation of Data Encryption Card Based on PCI-E Bus

基于PCI-E总线的数据加密卡设计与实现

The encryption card communicates with PC or industrial control computer by PCI-E interface .

设计的加密卡是通过PCI-E接口与PC机或者工控机进行通信。

A Windows Vista-based computer that uses a PCI-E graphics device may stop responding when you wake the computer from sleep .

当您将使用PCI-E图形设备的基于WindowsVista的计算机从睡眠模式唤醒时，该计算机可能会停止响应。

This paper use the DDK to develop the driver of the PCI-E digitizer to control it and to high efficiently read the data to the computer .

用DDK开发了驱动程序，实现了计算机对数字化仪板卡控制和高效数据读取。

This design uses two-port Random Access Memory ( RAM ) in FPGA as data buffer , so it is very convenient because PCI-E bus and local bus can accesses it though respective port .

为了增加系统的灵活性，在FPGA中设计了双端口随机存储器（RAM）作为数据的缓存区，PCI-E总线和本地总线可以通过各自的接口对其独立的访问。

The hardware of the system utilizes PCI-E bus bridge combined with FPGA structure , which is as the DMA data transfer controller . The PCI-E bus bridge is used to connect high-speed PCI-E bus and the local one .

系统硬件采用PCI-E总线桥+FPGA结构，在该结构中，PCI-E总线桥用于连接高速PCI-E总线与本地总线，担任DMA数据传输控制器。
