SystemC has become a very popular standardized language for the modeling of System-On-Chip (SoC) devices. However, due to the ever increasing complexity of SoC designs, the ever longer simulation times affect So C exploration potential and time-to-market. In order to reduce these times, we have developed a parallel SystemC kernel. Because the SystemC semantics require a high level of synchronization which can dramatically affect the performance, we investigate in this paper some ways to reduce the synchronization overheads. We validate then our approaches against an academic design model and a real, industrial application.
