Abstract
Introduced in an image data encoding device is a logic-memory combined chip in which a memory device and a signal processing device are combined. A logic part and a memory part can be connected to each other with a wide bus, allowing to improve processing capability of data transfer. However, the memory part of the logic-memory combined chip has a small capacity, so that an attempt to increase the capacity will lead to upsizing of the chip, resulting in an increase in costs. Therefore, in a processing that data transfer results in bottlenecks (i.e., motion search), image data is transferred to/from an internal memory capable of transferring data at high speed. In a processing that high-speed data transfer is not required, image data is transferred to/from an external memory.
