基于SOPC数字水印系统设计与实现

Digital Watermarking System Based on SOPC Design and Implementation

为了解决传统数字水印技术系统复杂、实时性差的问题,提出了一种基于SOPC数字水印系统设计,此系统以DCT算法和Arnold变换为理论依据,把整个系统集成到一个FPGA芯片上构成SOPC系统,SOPC系统是整个数字水印系统的信号处理和控制的核心,通过QuartusⅡ和NiosⅡEDS完成真个系统的定制。测试结果表明该系统具有运算速度快、稳定性强、实时性能好的优点。该系统具有很好的市场空间。

In order to solve the complexity of traditional digital watermarking technology systems,real- time problem of poor paper presents a digital watermarking system based on SOPC design,this system DCT algorithm and Arnold transform as the theoretical basis,the whole system into an FPGA chip SOPC system constituted,SOPC system is the digital watermarking system,signal processing and control of the core,through the Quartus Ⅱ and Nios Ⅱ EDS really a complete system customization. Test results show that the system has the computing speed,stability,real- time performance advantages. The system has a good market space.
