基于PCI Express总线的高速数据传输卡设计与实现

Design and implementation of a high-speed data transfer card based on PCI Express

通过设计PCI Express高速数据传输卡实现了地面控制台与计算机之间的高速数据传输。高速数据传输卡采用PLX公司的接口芯片PEX8311来实现PCI Express总线的接口逻辑,数据传输采用DMA方式,通过对信号源的自检验证了传输卡能够实时无误地传输数据。在硬件设计部分,主要对差分传输、PCI Express接口电路和FPGA逻辑控制模块进行了描述和设计。

A high-speed data transfer card based on PCI Express which realized high-speed data transfer between ground controller and computer was designed. Interface chip PEX8311 of PLX Co. was used to implemented interface logic, and the data transfer mode was DMA. Self-testing of data source can testify the function of the card. At the part of hardware implementation, the paper mostly presented LVDS transition ,PCI Express interface circuit and FPGA logic control module.
