A parallel bulk loading algorithm of M-tree is proposed in this paper, which takes advantage of the multi-core chips. The sequential bulk loading algorithm of M-tree consists of three steps: partition, recursion and aggregation, and we parallelize the first two steps. In the partition step, the whole dataset are split and assigned to several independent threads. Then, a tree-structure tasks graph...
H.264/AVC is a merging popular video coding standard which have new features. A H.264 open source, X264 code set, adopt motion estimation which consists of diamond search, hexagonal search, uneven multi-hexagon search, exhaustive search and hadamard exhaustive search. According to statistic values, the time-consuming of ME operations during HDTV(1920x1080p) encoding is about 60-80 percent within whole...
The emerging coding standard H.264 is mainly intended for video transmission in many areas. Considering the peculiarity of High-Definition TV (HDTV) encoding, the fast development of parallel technology and high-speed DSPs, the efficient hardware architectures were researched for the algorithm of H.264 encoding. After analyzing the experiment results from different platforms, we discussed the application...
