Abstract
A method and system for efficiently servicing a peripheral component event. In one embodiment of the present invention, peripheral component events are coalesced. The time interval between succeeding peripheral component events is determined. This time interval is then compared to a time threshold. This process continues until the time interval between succeeding peripheral component events meets or exceeds the time threshold. Once the time interval between succeeding peripheral component events meets or exceeds the time threshold, an interrupt is generated. By appropriately selecting a time threshold, idle periods are identified. Thus, the present invention generates interrupts when idle conditions exist, optimizing the generation of interrupts. By optimizing the generation of interrupts, the number of interrupts generated is reduced, minimizing the CPU overhead associated with the servicing of interrupts.
