Abstract
A power consumption of a semiconductor integrated circuit is reduced. A semiconductor integrated circuit comprises a first path P1 for performing data processing in a data processing circuit and a second path P2 for bypassing the data processing circuit or for performing data processing in a simplified circuit. The semiconductor integrated circuit exclusively selects the first path and the second path depending on an operational mode, and stops a data input into a path that is not selected, resulting in a reduction of the power consumption.
Claims4
A semiconductor integrated circuit comprising a data processing circuit that inputs data, performs a predetermined operational processing to the inputted data, and outputs data that is different from the inputted data, and the semiconductor integrated circuit having operational modes including (i) performing data processing in the data processing circuit, and (ii) bypassing the data processing circuit or performing data processing in a simplified circuit which is a simpler circuit than the data processing circuit, the semiconductor integrated circuit comprising:
- a first path that inputs data into the data processing circuit, performs the predetermined operational processing to the inputted data, and outputs data that is different from the inputted data;
- and
- a second path that (i) bypasses the data processing circuit and outputs the same data as the inputted data, or (ii) inputs the data into the simplified circuit, which performs another predetermined operational processing to the inputted data;
- wherein the first path or the second path is exclusively selected depending on an operational mode to stop the data input into a path that is not selected.
