    • In some embodiments, the inventions include a chip having a status register circuit coupled to conductors to receive interrupt event signals to provide source signals corresponding to the interrupt event signals. The chip also includes a control register circuit to provide source enable signals for selective ones of the interrupt sources, and a re-arming logic circuit coupled to the conductors to receive the interrupt event signals and provide a re-arming signal. The chip further includes first logic circuit to receive the source signals, the source enable signals, and the re-arming signal to provide an initial interrupt signal, and message signaled interrupt (MSI) signal pulse generation logic to receive the initial interrupt signal and provide an MSI signal in response thereto. Other embodiments are described and claimed.
    • 在一些实施例中,本发明包括具有状态寄存器电路的芯片,其耦合到导体以接收中断事件信号,以提供对应于中断事件信号的源信号。 该芯片还包括控制寄存器电路,用于为选择性的中断源提供源使能信号,以及耦合到导体的重新布线逻辑电路以接收中断事件信号并提供重新布防信号。 该芯片还包括接收源信号的第一逻辑电路,源使能信号和重新布防信号以提供初始中断信号,以及消息信号中断(MSI)信号脉冲产生逻辑以接收初始中断信号并提供 响应于此的MSI信号。 描述和要求保护其他实施例。
