  • Patent number: 7363408
    Abstract: An interruption control system includes an interruption message generator, a stop clock control module and an interruption status indicating path. The interruption message generator is used for decoding and identifying a message signaled interrupt (MSI) issued by a first peripheral device or a second peripheral device when interruption is to be conducted, and generates an interruption status indicating message in response to the message signaled interrupt (MSI). The stop clock control module is coupled to the interruption message generator and the CPU and de-asserts a stop clock signal that is previously asserted to have the CPU enter a power-saving state to have the CPU deactivate the power-saving state in response to the interruption status indicating message. The interruption status indicating path is used for transmitting the interruption status indicating message.

  • Patent number: 7206883
    Abstract: An interruption control system includes a first input/output interruption controller, a second input/output interruption controller, and an interruption control device bus. The first input/output interruption controller is coupled to a first peripheral device and a south bridge chip, and asserts a wake-up signal to the south bridge chip in response to a first interrupt signal issued by the first peripheral device so as to deactivate a power-saving state of the computer system. The second input/output interruption controller is coupled to a second peripheral device and a north bridge chip, and asserts a third interrupt signal in response to a second interrupt signal issued by the second peripheral device.

    Abstract: An interruption control system includes a first input/output interruption controller, a second input/output interruption controller and an interruption status indicating path. The first input/output interruption controller is coupled to a first peripheral device and a south bridge chip, and issues a wake-up signal to the south bridge chip in response to a first interrupt signal asserted by the first peripheral device so as to deactivate a power-saving state of the computer system. The second input/output interruption controller is coupled to a second peripheral device and a north bridge chip, and in response to a second interrupt signal asserted by the second peripheral device, generates a message signaled interrupt. The interruption status indicating path transmits the message signaled interrupt from the second input/output interruption controller to the south bridge chip to have the south bridge chip deactivate the power-saving state of the computer system in response to the message signaled interrupt.
