摘要
随着FPGA工艺的进步和性能的提升,型号装备的需求愈加向着小型化、低功耗和高度集成化发展。通过论述3种7系列XILINX FPGA远程更新的方案,比较得出一种适合微小卫星在轨更新的FPGA配置方案,并基于Artix-7与SPI Flash的硬件平台完成了对该配置方案的测试与验证。通过内部配置访问端口(ICAPE2)传输控制命令,用户可以自行选择跳转地址和加载时间,并在多个镜像中跳转。实验结果表明,该配置方案占用的硬件资源小,满足高复杂度配置文件的分时加载,降低了功耗,适应于当前微小卫星的设计潮流。
With the progress of FPGA technology and the improvement of performance,the demand of model equipment is increasingly toward miniaturization,low power consumption and high integration.Based on discussion of the three kinds of 7 series XILINX FPGA remote updating schemes,a FPGA configuration scheme suitable for micro-satellite in-orbit updating is obtained through comparison.At the same time,based on Artix-7 and SPI Flash hardware platform,the test and verification of the configuration scheme is completed.Through the internal configuration of access port(ICAPE2)transmission control command,users can choose their jump address and load time,and jump in multiple images.Experimental results indicate that the configuration scheme occupies less hardware resources,meets the time-sharing loading of highcomplexity configuration files,reduces power consumption,and adapts to the current design trend of micro satellites.
