<p><P>PROBLEM TO BE SOLVED: To solve the problem that although, for example, a SDRAM is usable as a reference memory for an encoder, it is considered that the memory for the encoder, a memory for drawing processing, or a memory used for processes with an external device is used in common for a recording medium to reduce the cost and size, but when the SDRAM is used in common, a device needs to perform high-speed processing to secure a bandwidth for each process and functions need to be limited for a limited bandwidth. <P>SOLUTION: Disclosed is the encoder (encoding device) 100 configured to store an image read out of the reference memory in an intermediate memory and then supply it from the intermediate memory 009 to a motion compensation unit 003, and halving access to the reference memory when the image is encoded using reference data common to different frames to improve usability; and the recording device. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
