With this approach, we are able to greatly strengthen the performance of the VOIM through exploiting parallel architecture of the digital signal processor (DSP) and parallel software design. In order to achieve high performance, we build up Master-Slave design architecture with the aid of TMS320C6701-DSP to construct a PHPS implementation scheme for the multimedia data encryption and decryption based on the framework of virtual-optics. In addition, we also adopt software pipelines and other optimization techniques to further strengthen the performance of such a strategy. This approach makes it possible for the VOIM to be realized in realtime applications in embedded systems for multimedia data security. Experiment results with digital image and digital audio signals show the validity of proposed approach. 收起
