  • Abstract:

    We present a new high speed cycle-approximate simulator, addressing an important, neglected category of multi-core systems: deeply-embedded cache-incoherent MPSoCs. We take advantage of the unique properties of these systems to increase the parallelism of the simulation. In doing so we achieve performance not possible using previous simulation techniques, without compromising the accuracy of the results. We present quantitative performance results across a large range of simulated NoC designs, comprising 1 to 64 cores. On average we simulate at 5.9 MIPS, with simulation speeds reaching 373 MIPS in the best case. Comparing against FPGA implementations we demonstrate that the simulator manages this with an average timing error of only 2.1%.
