实时图像水印在DSP系统中的设计与研究
Design and Research of Real-time Image Watermarking in DSP System
【摘要】 论述了基于TMS320C67x的实时图像水印处理系统的组成及其工作原理。通过采用一种新的算法,它以Winograd快速离散余弦变换(DCT)算法为基础,并利用TMS320C67x的基于超长指令(VLIW)的并行特征和流水线的执行方式提高DCT算法的性能,完成了实时图像水印的嵌入。
【Abstract】 This paper discusses the principle of image watermarking processing system based on TMS320C67x.In the system,with the algorithm based on Winograd discrete cosine transformation(DCT),the real-time image watermarking is well embedded by the parallelism of very long instruction word(VLIW) architecture and pipeline execution with high performance.
