ABSTRACT:
A system and method for managing service requests from peripherals connected to a personal computer or workstation by operating both in an interrupt mode and a polling mode, with selective transition therebetween. In one practice of the invention, peripheral device service requests are first managed on an interrupt basis, then transition to a polling mode when the interrupt rate exceeds a rate threshold, and subsequently revert back to the interrupt mode when the rate again decreases below a threshold. The transition is dynamic and situation adjustable by parameter selection both as to the number of service requests and as to the time interval used to initiate transition between the interrupt and polling modes.
