    Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of an information processor without making its processing performance lower than before. SOLUTION: The information processor that controls data transfer between devices is provided having an operational mode determining part for determining whether the information processor is to be operated in a normal mode or a power-saving mode according to the state of the power of the information processor, and a data transfer setting part that, when the information processor is determined to be operated in the power-saving mode, compares the state of the information processor in the mode with the state of the processor in the normal mode and sets the number of signal lines used in the data transfer at a smaller value.

    Abstract: PROBLEM TO BE SOLVED: To provide a superior information processing system with a power management function which reduce the power consumption by adequately lowering or stopping the operating frequency of a CPU by providing a power-saving means which places the CPU in power-saving mode for a specific time after the end of a transaction. SOLUTION: The CPU and a peripheral equipment are driven asynchronously and while the both communicate with each other, an interruption request is generated for a handshake and the CPU should respond speedily to the interruption request. The CPU, however, is in a mere wait state for the specific period after a specific transaction ends and the timing of the generation of a next interruption request is previously known. In this wait state, the operation of the CPU is lowered to save the electric power and the CPU is put back to its normal mode before an interruption request is generated to keep the maintainability of the system.
