摘要
FIR滤波器是一种常用的数字滤波器,数字图像空域滤波算法是图像预处理中常用的处理算法。结合FIR滤波器在数字图像空域滤波算法中的实际应用,研究其在实际的硬件电路设计与FPGA实现中的关键问题,并提出了如何有效缩短设计电路的关键路径和提高数据吞吐率的方法。最后在XINLINX公司的芯片Virtex-ⅡXC2V1000上设计了高速滤波器,实现了数字图像空域滤波算法。
FIR filter is one of the common digital filters,and digital image spatial domain fiter algorithms are important in digital image preprocessing. With application of the FIR filter in the digital image spatial spatial domain fiter algorithms, this paper presents the study of important problems of the corresponding hardware implementation. The most important problems are how to shorten the critical path and increase data throughput in the actual design,and this paper gives the solutions of the above problems. In the end,this paper designs and implements the spatial domain fiter algorithms in the Virtex-Ⅱ xc2vl000 chip.
