摘　　要：随着FPGA在雷达、通信领域等信号处理的广泛应用,FPGA资源成为限制信号处理算法工程应用的瓶颈。如何实现FPGA资源利用的最大化,成为工程上急需解决的问题。文章采用一种网络控制命令触发FPGA完成多重配置的方法,实现不同功能程序的切换。通过在信号处理板上的工程验证,该方法具有可操作性、灵活有效,解决了实现不同程序需要重复烧写程序的烦琐步骤,节省了人力物力。同时可用较少的逻辑资源完成需要更多逻辑资源才能实现的算法功能,提高了FPGA的资源利用率,降低了硬件设计的复杂性,在工程应用上具有很大的参考意义。Nowadays FPGA is used widely in signal processing of radar and communication domain,but FPGA resource has become the bottleneck in engineering application of signal processing algorithm.How to maximize the use of FPGA resource has become a problem which is needed to be resolved urgently.A method is applied to trigger FPGA to reconfigure and multiboot,and to switch different functional program in the paper.Through the engineering verification on the signal processing board,the method is easy to operate,flexible and effective.It solves the tedious steps of burning programs repeatedly to implement different programs,and reduces manpower and material resource.At the same time,the algorithm which needs more resource can be implemented to use less resource by this method.The method can improve availability of FPGA resource and reduce complexity of hardware design,and it also has great reference significance in engineering application.
