Abstract:
In an image processing device, a motion image decoding processing unit extracts a feature amount of a target image to be decoded from an input stream, and changes a read size of a cache fill from an external memory to a cache memory, based on the feature amount. The feature amount represents an intra macro block ratio in, for example, one picture (frames or fields), or a motion vector variation. When the intra macro block ratio is high, the read size of the cache fill is decreased.

Claim (Index 21):
An image processing method, comprising:\n (a) inputting a stream including motion images; (b) extracting a feature amount of a decoding target image from the stream; (c) specifying a read size from an external memory to a cache memory based on the feature amount; (d) determining occurrence of a cache hit or a cache error by comparing a request address to the external memory and tag data; when the cache hit has occurred, reading data corresponding to the request address, and supplying the data to a decoding processor; and when the cache error has occurred, reading data regarding the read size specified in step (c) from the external memory, and writing the data to the cache memory.
