摘　　要：为了能快速实现Laplacian算子高频增强功能,通过理论研究设计出该算子实现的硬件结构。提出一种调用仿真软件中宏功能块快速实现算法的硬件实现模式。详细介绍使用QuartusⅡ中Megafunctions宏功能模块库实现3×3模板Laplacian算子的过程。通过实验结果表明,用该方法实现的算子能够取得良好的滤波效果,且设计方便、有效,为相似功能模块的设计提供了新思路。In order to implement Laplacian algorithm,a new hardware implement frame based on research of the algorithm is designed. A fast hardware design model using Megafunctions in the development software is proposed. Depict the process of making use of QuartusⅡ＇s Megafunctions library to implement the 3 × 3 Laplacian algorithm, the results of experiment show that the method can receive good results in imagesr enhancement, the design method is simple and available,also provides a new thought for similar design.
