摘　　要：为提高盲图像复原的处理速度,以Xilinx公司的Virtex-4 LX80 FPGA芯片为平台,使用Verilog硬件描述语言,在合理利用硬件资源的条件下,实现了SeDDaRA盲图像复原算法。该算法结构简单、易于实现,能提高处理速度,较好的解决资源、速度与功耗三者之间的矛盾,具有较好的可扩展性。In order to speedup the process of blind image restoration,implement SeDDaRA image restoration algorithm using Verilog hardware description language on Xilinx Virtex-4 LX80 platform.Through optimizing algorithms and structures,with conditions of efficiently using of hardware resource,the utility of the parallel algorithm is exploited more efficiently in the design,and the trade-off between speed,area and power has been well handled.The algorithm is also easy to enlarge.
