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.
