Abstract
A gateway card is connected to an information processor, and receives and transmits data between different networks. The information processor has a normal power mode and a power saving mode. A switching unit connects a memory with the information processor if the information processor is in the normal power mode, or to the gateway card if the normal power mode of the information processor is changed to the power saving mode.
Claims33
A gateway card that is connected to an information processor and that receives and transmits data between different networks, the information processor having a normal power mode and a power saving mode, the gateway card comprising:
- a switching unit that connects a memory with either the information processor or the gateway card;
- and
- a switch control unit that controls the switching unit to connect the memory to the information processor when the information processor is in the normal power mode, and controls the switching unit to connect the memory to the gateway card when the normal power mode of the information processor is changed to the power saving mode.
A gateway device comprising:
- a memory;
- an information processor with a power control unit that shifts an operation status of the information processor from a normal power mode to a power saving mode and vice versa based on a predetermined condition;
- and
- a gateway card that is connected to the information processor and that receives and transmits data between different networks, the gateway card including
- a switching unit that connects the memory with either the information processor or the gateway card;
- and
- a switch control unit that controls the switching unit to connect the memory to the information processor when the information processor is in the normal power mode, and controls the switching unit to connect the memory to the gateway card when the normal power mode of the information processor is changed to the power saving mode.
A method of controlling a gateway card, which is connected to an information processor and which receives and transmits data between different networks, the information processor having a normal power mode and a power saving mode, the method comprising:
- connecting the information processor to a memory when the information processor is in the normal power mode;
- and
- connecting the gateway card to the memory when the normal power mode of the information processor is changed to the power saving mode.
A method of controlling a gateway device having a memory;
- an information processor with a normal power mode and a power saving mode, wherein the normal power mode is changed to the power saving mode and vice versa based on a predetermined condition;
- and a gateway card that is connected to the information processor and that receives and transmits data between different networks, the method comprising:
- connecting the information processor to the memory when the information processor is in the normal power mode;
- and
- connecting the gateway card to the memory when the normal power mode of the information processor is changed to the power saving mode.
A computer program that realizes on a computer a method for controlling a gateway card, which is connected to an information processor and which receives and transmits data between different networks, the information processor having a normal power mode and a power saving mode, the computer program making the computer execute:
- connecting the information processor to a memory when the information processor is in the normal power mode;
- and
- connecting the gateway card to the memory when the normal power mode of the information processor is changed to the power saving mode.
