ABSTRACT:
The invention saves power by supplying minimum clocks required for respective blocks. In a clock control system that supplies clocks to a plurality of blocks, such as a CPU-4, a bus, a peripheral circuit and other circuits, a clock supplied from a clock oscillator is supplied to clock control sections that are connected to the blocks, respectively. The clock is converted by the clock control sections into clocks with minimum clock numbers required to operate the blocks, respectively, and supplied to the blocks.
