FC网络通信中PCIe的接口的设计与实现

PCIe总线具有点对点串行连接、双通道、高带宽、链路数可选、在软件层与PCI保持兼容等特点,在嵌入式领域得到越来越广泛的应用。以XC5VFX130T芯片为硬件核心,分析PCIe的协议原理和XC5VFX130T芯片内嵌的PCIE Endpoint block硬核模块结构,实现具有PCIe系统主机接口的FC总线接口板卡,实现的功能和性能经过仿真和FPGA实现,达到了设计要求。

Design and Achievement of PCIe Interface on FC Communication

The feature of the PCIe Bus could include the Point-to-Point series connection,Dual-channel,High-bandwidth,Optional number of lanes,Compatible with PCI in the software level and so on.Moreover,this technique has been largely implemented in the field of embedded system.This paper proposed a new methodology which considered the XC5VFX130T core as the key component of hardware.By using probably analyzing in principle of PCIe and PCIE Endpoint block that has been embedded into XC5VFX130T,the PCIe inside of FC bus interface board has been achieved successfully.Besides that,the relevant function and performance have also been accomplished and satisfied the requirement according to simulation and FPGA achievement methodology.
