PACKET EXCHANGE FOR CONTROLLING SYSTEM POWER MODES

PROBLEM TO BE SOLVED: To provide a method in order to change an operational state of a resource within a computing system that is shared by a plurality of components of the computing system so that the computing system's power consumption is altered. SOLUTION: One feature of the present invention relates to a method having a step of transmitting a plurality of packets to the respective transmitting destinations by transfer between two or more nodes via a packet base network which is not a shared media bus or ring in the computing system in order to alter power consumption of the computing system, and in order to alter operating states of a power source and/or a clock source in the computing system shared by a plurality of components of the computing system, each of the plurality of packets includes the same piece of information regarding alteration of the power consumption in order to notify the respective receivers of alteration of the operating states, the packet base network is provided between one or more processor and a memory controller which transfer mutually executable instructions via the packet base network.
