Abstract
A data transfer control system for controlling data transfer between a first electronic apparatus coupled to a first bus and a device coupled to a second bus including a coupling control unit that issues an instruction to execute attachment to the first bus before power supply to the device is turned on, a bus state monitoring unit that detects whether or not the first bus enters a reset state after attachment and a power supply control unit that implements power supply control to turn on power supply to the device if a reset state of the first bus is detected.
Claims11
A data transfer control system for controlling data transfer between a first electronic apparatus coupled to a first bus and a device coupled to a second bus, comprising:
- a coupling control unit that issues an instruction to execute attachment to the first bus before power supply to the device is turned on;
- a bus state monitoring unit that detects whether or not the first bus enters a reset state after attachment;
- and
- a power supply control unit that implements power supply control to turn on power supply to the device if a reset state of the first bus is detected.
A program for controlling data transfer between a first electronic apparatus coupled to a first bus and a device coupled to a second bus, the program causing a computer to execute processing comprising:
- issuing an instruction to execute attachment to the first bus before power supply to the device is turned on;
- detecting whether or not the first bus enters a reset state after attachment;
- and
- implementing power supply control to turn on power supply to the device if a reset state of the first bus is detected.
