Abstract

In this paper, a novel energy-efficient concurrency control protocol, called conditional abortable stack resource policy (CA-SRP), is proposed for scheduling of dependent real-time tasks with abortable critical sections. Under the CA-SRP, a critical section is allowed to be aborted only if its re-execution is more energy-efficient than the blocking of higher priority tasks. The CA-SRP dynamically determines the appropriate processor speed for executing tasks on a DVS processor so that the energy consumption can be reduced. The capabilities of the CA-SRP were evaluated by a series of experiments, for which we have some encouraging results.
