ABSTRACT:
A task scheduling method for a real time computer system having automatic memory management or some other resource that is consumed in terms of a bit rate. The method ensures that non critical tasks do not prevent the timely execution of critical tasks. Each task is evaluated in terms of its rate of consumption of the resource. This rate is controlled by assigning each task a consumption quota and keeping track of the consumption of each task as it executes. The task is required to relinquish its processor time if it attempts to consume more than its quota.
