DATA PROCESSING CIRCUIT FOR REDUCING POWER CONSUMPTION BY USING CLOCK CONTROL

摘要

PROBLEM TO BE SOLVED: To provide a circuit which operates while reducing power consumption in accordance with throughput of blocks by individually supplying clocks of optimal frequencies to function circuits as needed.

SOLUTION: A data processor includes, for example, a reception buffer 101 or 102, a circuit 200 for detecting an effective data amount within the reception buffer, and clock supply circuits 201 and 206 for supplying clocks of different frequencies to circuit blocks in accordance with the amount detected by the detection circuit.
