Abstract: An interrupt request generating process can include determining a first interrupt triggering event has occurred after a predetermined period of time in which no interrupt triggering event occurred. In response to determining that the first interrupt triggering event has occurred, the interrupt request generating process may generate a first interrupt request without adding an intentional delay, and initiating a timer configured to expire after a predetermined time interval. When a second interrupt triggering event is determined to have occurred before the timer expires, a second interrupt request is delayed from being generated until the timer expires.
