標題: | Multiprocessor frequency locking for real-time task synchronization | 作者: | Chen, Y.-S. Chang, L.-P. TEI-WEI KUO |

The problem complexity comes from the complexity in multiprocessor task scheduling and the difficulty in the trading of priority inversion with energy consumption. In this paper, a multiprocessor task synchronization protocol is proposed by locking the frequency of each (co-)processor and synchronizing resource sharing of tasks in a systematic way and with cross-(co)processor considerations. The well-known Priority Ceiling Protocol is taken as an example for its extension on energyefficient real-time multiprocessor scheduling. The objective is to minimize the energy consumption of a task set and, at the same time, meet the task deadlines. The capability of the proposed methodology is evaluated by a series of experiments, for which encouraging results are presented. Copyright 2008 ACM. |
