| Abstract(in English) | Simultaneous Multithreading is a processor architecture that combines the superscalar with fine-grained multithreading. Although it is expected to come to support real-time systems, very few works have been done in the area of real-time processing in SMT processors in the past. One of SMT-specific characteristic is an execution time jitter. From the viewpoint of real-time processing, it would be a critical problem since there is a possibility of deadline miss if the execution time fluctuates. In this paper, we examine a behavior of the existing real-time scheduling algorithm on an SMT processor and clarify the issues. We then design and implement a new scheduling algorithm which enables real-time processing on an SMT processor and evaluate it. The result proved that our algorithm held execution time jitter low compared to EDF algorithm. |
