利用单板机+FPGA实现对FPGA的在线配置

由于某雷达整机联调的需要,为了可以在雷达开机转动时在线配置测试更改后的FPGA调试程序,可以用单板机上存放的配置FPGA所需的bit文件通过CPCI总线访问另一片接口FPGA去配置主运算FPGA,从而解决了运行条件下实时调试程序的问题,还可以应用于多种模式分时复用FPGA的场合。

FPGA Online Configuration Achieved by using SBC and FPGA

During a whole radar system adjustment, it is required that FPGA should be able to be configured online with tested and modified debugging program when the radar is operating. In order to meet this requirement, we use a . bit file （for FPGA configuration） saved in a single board computer （SBC） to access another interfacing FPGA via CPCl-bus to configure master operational FPGA, program debugging in real-time under the condition of running is achieved. This approach can also be applied to multiple patterns of time-sharing multiplexing FPGA.
