Multi-granularity sampling for simulating concurrent heterogeneous applications
Detailed or cycle-accurate/bit-accurate (CABA) simulation is a critical phase in the design flow of embedded systems. However, with increasing system complexity, full detailed simulation is prohibitively slower than the hardware being simulated. In this paper, we present an approach that uses the sampling technique to speed up the design flow of Multiprocessor System-on-Chip (MPSoC) systems. Based on the dynamic behavior of the applications running concurrently, our method dynamically chooses between multiple granularities of the sampling phase. The similarities of the execution phases for all possible granularities are first analyzed, then transitions between phase overlaps are discretized. To facilitate the detection of repetitions, one phase, with an appropriate granularity, is chosen per process. Unlike most other proposals, the associated performance is usually accurate enough not to need repeated resampling. The use of checkpointing in conjunction with our approach is simplified...
