Abstract
A system and method for dynamically calculating the maximum amount of time a peripheral component event can be stored before generating a corresponding interrupt. Specifically, in this embodiment, the host computer is adapted to have a peripheral component removably coupled thereto and is adapted to operate a peripheral component driver. The peripheral component driver, in turn, is adapted to dynamically calculate the maximum amount of time a peripheral component event can be stored before generating a corresponding interrupt. The peripheral component of this embodiment is adapted to store the peripheral component event and cause the generation of an interrupt when the peripheral component event has been stored for the maximum amount of time. Once again, the present embodiment, like the previous embodiments, reduces the frequency with which interrupts are generated, and minimizes the CPU overhead associated with the servicing of interrupts.
