摘要
阐述了可重构技术在密集型计算领域的广阔应用前景。基于该技术的数据加密系统兼具了硬件的效率和软件的灵活性,有着重要的理论与实际意义。在可重构系统基础上设计并实现了数据的加密计算。给出了一种通用的加密模块接口的设计方法,用于实现对加密模块的状态控制,并向接口用户提供一个简单易用、与底层实现无关的接口。在XUP开发平台上,用AES和DES数据加密算法进行了功能验证和性能分析,表明该方法行之有效。
The applications ofreconfigurable technology in computing-intensive area are generally introduced. Data encryption system based on reconfigurable technology can provide hardwire efficiency and software flexibility. It has the important theoretical and practical significances. A universal interface design method for encryption module is presented, which gives an effective way to control the status of the user module, independent of the lower level implementation. The validation and performance analysis are demonstrated by the AES and DES encryption on Xilinx Virtex-2 FPGA. At last, this design is proved to be effective.
