Abstract

A system for reading texture data from a memory without need to use a cache unit in such a manner that the read speed is not affected by the size of the memory, wherein a memory address is supplied to a memory address comparing unit, a memory address comparing unit compares the memory address of the current pixel and the memory address of the immediately preceding adjacent pixel, the compared result being supplied as information to a compared result storing unit which stores the information. A memory accessing unit receives a memory address different from the memory address of the adjacent pixel aid reads texture data the corresponding address in a memory, the texture data being stored in a texture data storing unit. A texture data restructuring unit reads texture data from the texture data storing unit corresponding to the information read from the compared result storing unit and restructures the texture data accordingly.
