  • Interrupt processing unit for preventing interrupt loss
    Patent number: 9026705
    Abstract: Techniques are disclosed relating to systems that allow sending and receiving of interrupts between processing elements. In various embodiments, a system includes an interrupt processing unit that in turn includes various indicators corresponding to processing elements. In some embodiments, the interrupt processing unit may be configured to receive an interrupt and determine whether a first processing element associated with the interrupt is available to receive interrupts. The system may initiate a corrective action if the first processing element is not available to receive interrupts. In some embodiments, the corrective action may include redirecting the interrupt to a second processing element. In some embodiments, the interrupt processing unit may include a dropped interrupt management register to store information corresponding to the second processing element.
