The accuracy of simulated cycles in high-level simulators is generally less than the accuracy in detailed simulators for a single-core systems, because high-level simulators simulate the behaviour of components rather than the components themselves as in detailed simulators. The simulation problem becomes more challenging when simulating many-core systems, where many cores are executing instructions concurrently. In these systems data may be accessed from multiple caches and the abstraction of the instruction execution has to consider the dynamic resource sharing on the whole chip. The problem becomes even more challenging in microthreaded many-core systems, because there may exist concurrent hardware threads. Which means that the latency of long latency operations can be tolerated from many cycles to just few cycles. We have previously presented a simulation technique to improve the …
