High-performance microprocessors, e.g., multi- threaded and multicore processors, are being imple- mented in embedded real-time systems because of the increasing computational requirements. These com- plex microprocessors have two major drawbacks when they are used for real-time purposes. First, their com- plexity difficults the calculation of the WCET (Worst Case Execution Time). Second, power consumption requirements are much larger, which is a major con- cern in these systems. In this paper we propose a novel soft power-aware real-time scheduler for a state-of-the-art multicore multithreaded processor, which implements dynamic voltage scaling techniques. The proposed scheduler reduces the energy consumption while satisfying the constraints of soft real-time applications. Different scheduling alternatives have been evaluated, and ex- perimental results show that using a fair scheduling policy, the proposed algorithm provides, on average, energy savings ranging from 34% to 74%. |
