适应远程升级的FPGA配置方法

针对现场可编程门阵列（FPGA）远程升级的需求，介绍了几种可实现的适应远程升级的FPGA配置方法。通过对器件配置原理的分析比较，结合工程实践，重点提出了两种基于主动串行（AS）模式的配置新方法：通用型远程升级配置方法和新型远程升级配置方法。这两种配置方法对于单板调试没有影响，易于实现远程升级而不增加任何分离器件，对于成本和功耗的降低也有较明显的优势。

Research on Configuration Schemes for Remote Upgrade of FPGA

Several FPGA configuration schemes are introduced in this paper to meet increasingly strong demand of the remote upgrade of field programmable gate （FPGA）.Based on the analysis and comparison of the configuration schemes mentioned and combined with practice of project, this paper proposes two new configuration schemes based on Active Serial（AS） mode： the universal remote upgrade configuration scheme for common FPGA devices and the new remote upgrade configuration scheme for new FPGA devices. The two schemes have hardly any influence on board level debug. With no more devices to be added, they can be implemented on the plat. They have obvious advantages in cost and power consumption.
