Digital watermark is the effective way to realize the copyright protection, the digital watermark application with the multi-core technology is being more and more widely in embedded systems today. This paper proposes a way that NiosII dual-core realizes the digital images embedding watermarking, including the DCT algorithm, NiosII dual-core parallel processing, barrier synchronization mechanism, realizing digital images embedding watermarking. The experiment results shows that dual-core is more efficient than single-core, images embedded with watermark comparing with the original one have no change in vision.
