摘要/Abstract

摘要： 为了实现某星载差分吸收光谱仪CCD驱动电路的FPGA在轨重构功能，介绍了一种基于STM32的星载FPGA在轨重构的地面验证方法。分析了实际的重构方案并提出地面实验方案，从硬件设计和软件设计两个方面阐述了地面实验的总体方案。经过实验室测试验证，上位机发送和回读的数据一致，STM32可以模拟JTAG协议实现加载配置数据至FPGA，重构时间可缩短至800 ms。该方法的硬件和软件设计是合理可行的，可以完成对FPGA功能的修改。该方案可为CCD驱动电路的FPGA重构方法提供参考。

Abstract: To realize the FPGA on-orbit reconfiguration function of a CCD drive circuit of a spaceborne differential absorption spectrometer, an MCU-based ground verification method for on-board reconfiguration of an FPGA. The actual reconfiguration scheme is analyzed and a ground experiment scheme is proposed. The overall scheme is described from two aspects of hardware design and software design. Arter the test validation in the laboratory environment, it was found that the data sent and read back by the host computer were consistent and STM32 can simulate the JTAG protocol to load configuration data to the FPGA. Reconfiguration time can be shortened to 800 milliseconds. The design of hardware and software is reasonable and feasible. It can complete the modification of FPGA functions. This solution can provide a reference for the CCD driving circuit FPGA reconfiguration method.
