Abstract: PURPOSE: A bus mediation apparatus and method thereof are provided to improve the performance of a bus system by solving asymmetric performance distribution problems. CONSTITUTION: A collecting unit(110) collects accumulation mediation information and mediation requests for masters. A QoS(Quality of Service) analysis unit(120) calculates delaying time for the masters based on kinds of the masters and the mediation requests and the accumulation mediation information by classifying the kinds of the masters based on master properties. A mediation unit(130) creates bus mediation signals based on the kinds of the master and the delaying time.

Abstract: PURPOSE: An image processing method using a block based parallel process SPIHT(Set Partitioning In Hierarchical Trees) is provided to compressing an image by dividing a bit plane into blocks. CONSTITUTION: If 4X4 blocks are significant, the 4X4 blocks are divided into 4 2X2 blocks(3). If the 4X4 blocks are not significant in a previous bit plane and significant in a current plane, the significance of the 4X4 block is generated(5). The queue bit alignment bit(13) is outputted(7). An absolute value bit is outputted to the 2X2 blocks. If the pixel is significant in the current bit plane, a code bit is successively outputted(9).
