IMAGE PROCESSOR AND METHOD FOR MEMORY ACCESS CONTROL

摘要

An image processor includes a memory including multiple memory banks each having multiple unit storage areas and holding an image, an image processing unit that processes an image, and an access controller that controls an access from the image processing unit to the memory. In storing the image in the memory, the access controller splits the image in multiple groups of unit pixel data pieces including pixel data of multiple columns by multiple rows, and stores groups of unit pixel data pieces aligned in at least two columns in a pixel space in the same unit storage area in the same memory bank.
