Image data processing apparatus

摘要

An image data processing apparatus capable of performing processing at a high speed comprising a DRAM for storing display data including a plurality of first pixel data respectively indicating colors of a plurality of pixels arranged in a matrix and able to be simultaneously written with a plurality of first pixel data. Memory controllers are provided with a plurality of pixel data generation circuits provided corresponding to the plurality of first pixel data to be simultaneously written for performing color blending using the second pixel data and the third pixel data for blending a color indicated by corresponding second pixel data and a color indicated by third pixel data stored in the write address by a predetermined blending ratio to generate a new color so as to generate the first pixel data indicating the new color.
