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。
The composition and working principle of real-time image watermarking system based on TMS320C67x are discussed. Based on the Winograd DCT (Discrete Cosine Transform) algorithm and using the TMS320C67x VLIW-based parallel features and pipelining to improve the performance of the DCT algorithm by using a new algorithm, the real-time Image watermark embedding.
