We have the following achievements(1)High-performance graphics algorithm and its hardwareWe analyzed parallelism and locality of reference in a graphics algorithm based on the global illumination model, and designed a novel rendering pipeline architecture for this algorithm. In addition, we designed and developed a prototype hardware based on the architecture. Through the performance evaluation of the hardware, we showed its effectiveness for realizing interactive ray-tracing. Moreover, we designed a new high-performance algorithm for generating walkthrough animations.(2)Power-efficient memory mechanismFor design of the intelligent memory architecture for mobile devices, a low-power mechanism for on-chip memory system was designed. In this mechanism, memory modules are activated and inactivated based on their activity during the program execution. We clarified the relationship between activated memory modules and sustained performance, and showed the effectiveness of power-aware computing for on-chip cache memory.(3)Data compression algorithms for graphics hardware.We applied vector quantization to volume data set to achieve efficient data compression, and designed a visualization algorithm that can directly visualize the compressed volume data. We also designed a novel data compression algorithm using data clustering for graphics hardware
