Abstract
In this paper, we explored the scheduling problem of dependent real-time tasks that may access multiunit resources on a non-ideal dynamic voltage scaling (DVS) processor. Based on the stack resource policy (SRP) protocol and the earliest deadline first (EDF) algorithm, we propose an approach, called blocking-time stealing stack resource policy (BTS-SRP), for the scheduling of dependent real-time tasks. Under the BTS-SRP, tasks are executed at proper processor speeds which are calculated according to the sufficient schedulability condition of the EDF and the SRP. In order to obtain more energy saving, a blocking-time stealing method is also proposed to dynamically adjust the processor speed. The experimental results show that the BTS-SRP is very effective in energy efficiency.
