Abstract:
1. A data processor comprising: a data input unit into which data is inputted; an input data storing unit in which said data inputted into said data input unit is stored; a signal processing unit operable to read out said data stored in said input data storing unit, and perform signal processing of data read from said input data storing unit; a signal processing control unit operable to control said signal processing unit to have said signal processing unit perform an intermittent operation by having said signal processing unit perform said signal processing at a processing speed faster than a speed at which said data is inputted into said data input unit; a clock/power source control unit operable to reduce electric power consumption of said signal processing unit and said signal processing control unit by restricting either or both a clock signal and an electric power to at least one section of said signal processing unit and said signal processing control unit in an inactive period of said intermittent operation; and an input monitor unit operable to monitor the volume of data in said input data storing unit, to request said clock/power source control unit to remove the restriction of either or both a clock signal and an electric power to at least one section of said signal processing unit and said signal processing control unit on the basis of said volume of data in said input data storing unit, and to request said signal processing control unit to move into an active period of said intermittent operation.
