Abstract
A detection unit detects input-request signals or receive signals that correspond to the input-request signals that are sent and received between a specific data-processing apparatus and another apparatus. A judgment unit then determines whether the data-processing apparatus is performing a specific process, based on the status of the data-processing apparatus and detection results from the detection unit. A supply-control unit controls whether or not to supply a synchronization clock to the data-processing means according to judgment results from the judgment unit.
Claims5
An apparatus comprising at least a first processing unit and a second processing unit, wherein
- the first processing unit performs first processing of input data and outputs the processed data, and
- the second processing unit performs second processing of data input from the first processing unit to the second processing unit, and outputs the processed data,
- the apparatus further comprising a power consumption management unit configured to judge whether the second processing unit is available to accept data input and the first processing unit is unavailable to perform data output, the power consumption management unit stopping supply of a clock to the second processing unit if an affirmative judgment is made.
