基于PCIe的FPGA动态配置设计与实现
首发时间:2011-10-18
摘要:随着现代处理器技术的发展,在互联领域中,使用高速差分总线替代并行总线是大势所趋。因此PCIe取代PCI,越来越多的应用在高速互联系统中。本文先简单介绍了FPGA的不同配置方法,然后描述了SelectMAP配置流程和数据格式。紧接着给出了作者所使用的PCIe子卡的系统结构。最后详述了SelectMAP配置方法的具体实现过程,包括FPGA程序设计和上位机应用程序设计。该配置方法灵活、快捷、可靠,可广泛应用于高速互联系统设计中。

Design and Implementation of FPGA's Dynamic Configuration Based on PCIe
Abstract:With the development of modern processor technology, using high-speed differential bus rather than a parallel bus is the trend in the interconnection field. Instead of PCI, PCIe is used more and more in high-speed Interconnection system. This paper briefly introduces the different configuration methods of FPGA, and then describes the SelectMAP configuration processes and data formats. Then it discribes the architecture of the PCIe card. Finally it gives a detail discription of SelectMAP's implementation process, including FPGA programming and application program design. This configuration method is flexible, fast and reliable, which can be widely used in high speed interconnection system design.
