To provide an integrated information processing unit that is capable of producing images and sounds of high quality. It includes a control unit, information processing units, and a merge unit. Each of the information processing units includes a counter for synchronization purpose. The information processing units performs a predetermined processing based on the measured value obtained by the counter for synchronization purpose. The control unit simultaneously provides a trigger of measurement of synchronization clocks to all counters for synchronization purpose and individually provides a reset signal to the counters for synchronization purpose which the reset signal is for initializing the measured value obtained by the counters for synchronization purpose. The merge unit merges information processed by the information processing units according to the unit of output (in frame) of, for example, a display device.
