基于PCI_mt64 IP核的PCI接口设计及在网闸高速数据通讯中的应用

Application of PCI Interface Design Based on PCI_mt64 IP Core in High-Speed Communication of GAP System

介绍一种使用MEGACOREIP核逻辑进行的高效的PCI接口设计方法。该方法可将PCI接口和PCI用户逻辑集成在一片FPGA里,可以对整个逻辑进行仿真调试。重点叙述了ALTERA公司提供的64位MASTER、TARGET接口IP核PCI_mt64的原理和结构,以及基于此IP核在网络隔离系统内外网之间实现高速数据通讯应用。

A method for implementing PCI interface with IP core is introduced in this paper.The PCI interface and local logic was integrated in only one FPGA in the design,so can easily simulate or debug the whole logic,through which time and cost of design are deduced.The emphasis of this paper was the element and structure of ALTERA Megacore pci_mt64,based on which an implementing method of PCI interface in high--speed communication of Physical Isolate GAP System.
