FPGA online update method based on dynamical reloading

在分析综合化电子系统中传统FPGA在线更新电路及方法局限性的基础上,提出了一种基于动态加载的FPGA在线更新方法,并详细介绍了该方法的设计、实现及验证。工程应用实测结果表明,基于动态加载的FPGA在线更新电路及方法,不仅避免了通过增加DSP才能实现FPGA在线更新,降低了成本和系统复杂度,而且避免了在线更新模块内置于FPGA功能应用程序中,减少了系统耦合和处理资源占用。

Based on the analysis of the limitations of the traditional FPGA online update methods in integrated electronic system,a FPGA online update method is proposed based on dynamical reloading,and the design,implementation and verification of this method are described in detail.The actual measurement results of engineering application show that,the FPGA online update circuit and method based on dynamical reloading not only reduces cost and circuit complexity by avoiding the need to increase DSP to realize FPGA online updating,but also reduces the system coupling and processing resources occupation by avoiding the online update module being built into the FPGA functional application program.
