We improve a method for single instruction, multiple data (simd) operations for two-dimensional patterns by use of image compression. In the method, image data is compressed with the novel encoding rule. The encoded data consists of a set of the pixel position where the pixel value is changed and the period of the pattern. The feature of the improved method is to consider the period of the patterns. And, desired processing is executed by specific operations equivalent to logical operations for the original data. We estimate effectiveness of the improved method. The method is implemented on a personal computer and compared with the simulator based on the conventional scheme. As results of estimation, it is verified that the computational costs of the method are about ten times as small as that with the conventional compressed scheme.
