一种基于光纤数据传输的多板卡软件程序烧写技术

A Multi-board Software Program Writing Technique Based on Optical-fiber Data Transfer

大型相控阵雷达信号处理中,雷达前端AD采样板数量较多,AD采样板内FPGA和DSP软件程序需要修改和更新时,需要对每块AD采样板进行程序烧写,增加了系统调试时间和调试复杂度。本文介绍了利用多根光纤将需要更新的FPGA和DSP程序上传至前端AD采样板,在板卡内完成程序烧写,较大程度节省了调试时间和简化了调试复杂度。

In large phased array radar signal processing, there is large number of radar front - end AD sampling board. When FPGA and DSP software programs need to be modified and updated, program on each AD sample board needs to be written, this will increase debugging time and complexity of system debugging. A technique of using multiple pieces of optical fiber to upload the FPGA and DSP program needed to be upgraded to front - end AD sampling board, on which the program writing is accomplished. Using this technique can save debugging time and simplify the debugging complexity greatly.
