Abstract
An input data controlling unit preferentially outputs pixel data of an area label for which the operation result is held in a cache. In regard to pixel data of an area label for which the operation result is not held, the input data controlling unit once accumulates the plurality of pixel data in an internal FIFO and then outputs the accumulated pixel data in a lump, to suppress occurrence of a cache miss in the cache. Besides, when accumulating the pixel data in the FIFO, the input data controlling unit reduces a frequency that the area label is changed, by accumulating the pixel data in the FIFO until the FIFO comes to be full of pixel data as much as possible, thereby further suppressing the cache miss.
