Image data processing system and image data reading and writing method

摘要

An image data processing system with a memory performing burst read/write operations. The memory includes a memory cell array provided with memory cells arranged in a plurality of rows and a plurality of columns. The image data processing system further includes a controller for controlling an operation of reading/writing the image data from/to the memory. The controller divides the image data into a plurality of segments when a horizontal size of the image data is larger than a column width of the memory. An (I+1)-th (where I is a positive integer) segment includes a last burst data of an I-th segment, or the I-th segment includes a first burst data of the (I+1)-th segment. The respective segments correspond to the plurality of rows of the memory.
