摘　　要：随着互联网的普及和图像应用范围的不断扩大,对图像的处理提出了新的要求,即不仅要求对图像识别的准确,还要求达到实时处理,因此系统以高性能数字信号处理器ADSP-BF561和大规模现场可编程门阵列(FPGA)作为核心,结合离散整数小波变换,在硬件系统上实现提升方法的整数小波变换和Mallat算法小波变换,取得了较好的试验效果。With the extensive application of Intemet and image, some new requirements in image processing, such as accurate image recognition and real-time processing, are to be performed well by wavelet transform.So the system takes the high-performance digital signal processor ADSP-BF561 and the large-scale field - programmable gate arrays （FPGA） as the key, and combines discrete wavelet transform. The integral wavelet transform and wavelet transform algorithm with Mallat are realized on hardware system. Finally, the experimental results are satisfying.
