Abstract: A rendering apparatus includes a memory device, a cache memory, a cache control unit and a rendering process. The memory device stores image data. The cache memory executes transmission/reception of the image data to/from the memory device. The cache memory includes a plurality of entries, each of which is capable of storing the image data. The cache control unit manages data transfer between the memory device and the cache memory and stores information relating to a state of the cache memory. The cache control unit stores, in association with each of the entries, identification information of the image data transferred from the memory device to the entry of the cache memory and transfer information which is indicative of whether the image data is already transferred to the entry or not. The rendering process unit executes image rendering by using the image data in the cache memory.
