Concurrent phase classification for accelerating MPSoC simulation

To rapidly evaluate performances and power consumption in design space exploration of modern highly complex embedded systems, new simulation tools are needed. The checkpointing technique, which consists in saving system states in order to simulate in detail only a small part of the application, is among the most viable simulation approaches. In this paper, a new method for generating and storing checkpoints for accelerating MPSoC simulation is presented. Experimental results demonstrate that our technic can reduce simulation time and the memory size required to store these checkpoints on a secondary memory. In addition, the necessary time to load checkpoints on the host processor at runtime is optimized. These advantages speedup simulations and allow exploration of a large space of alternative designs in the DSE.
