PROBLEM TO BE SOLVED: To provide an image processor and its method capable of avoiding increases in area and electric power, simplifying a memory access mechanism, reducing design load, and being independent of a memory system. SOLUTION: A rasterization engine 32 accesses the memory through a memory interface 22. A cache system 324 is provided between a texture pixel engine which processes texture and pixel levels and the memory interface. The function of generating the true address in a way depending on an image memory architecture is divided between the method of a command that is independent of the image memory architecture and the method of delivering data, whereby the memory access of image processing is separated into a cache that does not depend on the image process memory architecture.
