Abstract
A system and method for dynamically calculating the quantity of peripheral component events to coalesce. In one embodiment, a host computer is adapted to have a peripheral component removably coupled thereto. The host computer is further adapted to operate a peripheral component driver. The peripheral component driver of the present embodiment is adapted to dynamically determine the quantity of peripheral component events to coalesce. The peripheral component is adapted to coalesce the determined quantity of the peripheral component events. Furthermore, the peripheral component is adapted to cause the generation of an interrupt upon the occurrence of the determined quantity of the peripheral component events. Also, the present embodiment periodically re-determines the quantity of the peripheral components which should be coalesced. As a result, the present invention dynamically optimizes the frequency with which interrupts are generated, thereby minimizing the CPU overhead associated with the servicing of interrupts.
