  • Multiple interrupt handling method, devices and software
    Patent number: 7953906
    Abstract: A device, method and software for handling multiple interrupts in a peripheral device are disclosed. The disclosed method includes, upon a hardware event in the peripheral device recording the hardware event and determining an acceptable period before which an interrupt should be generated to service the event. A timer at the peripheral device is adjusted as needed to maintain a value within the acceptable period. Upon expiry of the timer a single interrupt is generated to a processor interconnected to the peripheral device. In response to the single interrupt, software code is executed on the processor to service un-serviced hardware events for which an indicator has been recorded.
