<p><P>PROBLEM TO BE SOLVED: To provide a data processor which can regenerate and look/listen to a continuous compressed data such as AV regeneration and looking/listening of broadcasting, by a reduced electric power consumption. <P>SOLUTION: The data processor includes a decoding part 11 for outputting a decoded data decoded with the compressed data read out from the first data storage part 21, the second data storage part 22 for storing the decoded data, a DA converter 41 for reading out the decoded data from the second data storage part 22 in real-time, to be converted into an analog signal, the first control part 52 for controlling the decoding part 11, to be operated intermittently, by executing processing from the reading of the compressed data to the storage of the decoded data, at a speed faster than that in real-time, a clock/electric power control part 54 for limiting the electric power consumption in an upstream of the second data storage part 22 during a stopped time of the intermittent operation, the second control part 53 for outputting a control signal in response to a storage state of the decoded data in the second data storage part 22, and a start-up control part 55 for releasing the limitation of consumed electric power by the clock/electric power control part 54, by receiving the control signal. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
