Abstract (in Japanese) (See Japanese page) 
(in English) A cache memory subject to the process of conventional raster scan order is not suitable for efficient data process with locality of reference for more than 2-dimensions. For example, for motion estimation process which account for approximately 80% of the encoding process, even speeding up by the high parallel of the SIMD process, because it can not support 2-dimensional locality, frequent conflict miss or decline of transfer efficiency due to unnecessary data swap become the bottleneck. In this report, to eliminate the bottleneck, minimize conflict misses and unnecessary data swap, we proposed a cache memory with line and tile data accessibility which regard hierarchical tile data as conventional raster data to access and shown the function and configuration method of the proposed cache memory. Compared with conventional direct-mapped cache memory, it revealed that the increase of peripheral circuit scale is about 107% and both read and write process need one more cycle.
