Abstract
The invention provides a power control device for a computing unit, which is optimal for saving power. When MPEG data is supplied, a CPU starts decoding the MPEG data. The MPEG data is decoded by independently decoding video data and music data. When decoding the MPEG data, in each operation unit included in the MPEG data, the clock frequency of the CPU can be adjusted so as to reduce the power consumption of the CPU on the basis of the data length of the operation unit for a period during which the CPU performs an operation on the data in the operation unit.
