Abstract
A system and method for dynamically calculating a maximum allowable time interval which can lapse between peripheral component events before an interrupt is generated. In this embodiment, the host computer is adapted to have a the peripheral component removably coupled thereto and operate a peripheral component driver. The peripheral component driver in this embodiment is adapted to dynamically calculate a maximum allowable time interval which can lapse between peripheral component events before an interrupt is generated. The peripheral component is correspondingly adapted to cause the generation of an interrupt when the maximum allowable time interval has elapsed between successive ones of the peripheral component events. As a result, the present embodiment, like the previous embodiment, reduces the frequency with which interrupts are generated, and minimizes the CPU overhead associated with the servicing of interrupts.
