Programmable embedded systems are ubiquitous nowadays, and their number will even further increase withthe emergence of Ambient Intelligence. One of the first challenges for embedded systems is mastering the increasing complexity of future Systems on Chip (SoC). the complexity will increase irremediably because the applications become more and more demanding and the algorithmic complexity grows exponentially over time.

the wavelet packet provides an accurate method for image fusion. However, the computation and time cost will increase withthe size of image. therefore it is difficult to achieve real-time fusion. After having analysed the wavelet packet based image fusion algorithm on the single computer, according to the time complexity and the parallel character of the wavelet packet algorithm, we propose a wavelet packet based parallel image fusion algorithm under the situation of distributed storage. Based on the data local property of wavelet packet transform, we achieve the algorithm on the MPI (Message Passing Interface) parallel computing platform, which is composed by Pentium PC and 1000 Mbps Ethernet. the efficiency of parallel computing is studied under different image size and different cluster size. the experimental result shows that the algorithm has good parallel computing property.

this paper introduced a brand-new, paralleldistributed and extensible framework of 3D visualization system put forward by the author, which is based on JAVA techniques. the author designed parallel process method which works together withthe terrain simplification algorithm to improve the speed of the 3d interactive system. As shown from the experiment results, the designed framework achieves a satisfying effect and a high efficiency when dealing withthe display of 3D visualization even with a huge data quantity, which owes to the mechanism of assorting the visualization algorithms on the Client side withthe data designation and transfer on the Server side.

A multimedia contents are distributed to peers and a contents peer which holds contents can provide other peers withthe contents in peer-to-peer (P2P) overlay networks. Multimedia streaming is more significant than downloading ways in multimedia applications from security and economical reasons. We discuss distributed multi-source streaming models. Here, a collection of multiple contents peers in parallel transmit packets of a multimedia content to a leaf peer to realize the reliability and scalability. Even if not only some number of peers stop by fault and are degraded in performance but also some number of packets are lost and delayed, a leaf peer can receive a content at the required rate. We discuss how to allocate packets to each contents peer. We discuss a gossip based, DAG-based coordination protocol (DCoP) to synchronize multiple contents peers. We evaluate DCoP in terms of how long it takes and how many messages are transmitted to synchronize multiple contents peers.
