Power control device for digital electronic device, processing device whose power is controlled by the power control device, and power management system for digital electronic device provided with the power control device

摘要

PURPOSE:To control the power of a digital electronic equipment by a logic system means by providing a control means which decodes the encoded power management instruction and outputs a control signal based on the decoded power management instruction. CONSTITUTION:A program storage section 11 outputs an instruction program written in a ROM 10 based on the micro order from a control instruction decoder 14. An address counter 12 accesses to the ROM 10 and a control instruction register 13 stores the instruction program written in the ROM 10. The control instruction decoder 14 decodes the instruction stored in the register 13 and outputs the micro order to an I/O controller and a register group 15. The register group 15 is provided with a register storing the instruction and data of power management to be given to the individual control part PR of the CPU and the instruction and data of power management which is given to the individual instruction control part PR for I/O controller.
