Based on analysis three typical parallel rendering technologies, the principle and architecture of large-scale virtual scene roaming system driven by PC machine were introduced. The parallel rendering means of sort-first and sort-last was presented and the results of each mode were given. By comparing the two parallel rendering means, the advantages and disadvantages of each means were discussed and...
For all video applications, large amounts of data are processed within a bounded time. These data are usually stored in a low-cost slow external DRAM which results in high memory bandwidth requirement. The memory bandwidth will dominate the system performance, especially for applications running on embedded systems. In this paper, we propose an effective dictionary-based compression and de-compression...
