Full System Simulation of Many-Core Heterogeneous SoCs Using GPU and QEMU Semihosting
Modern System-on-Chips (SoC) are evolving towards complex and heterogeneous platforms with general purpose processors coupled with massively parallel manycore accelerator fabrics (e.g. embedded GPUs). Platform developers are looking for efficient full-system simulators capable of simulating complex applications, middleware and operating systems on these heterogeneous targets. Unfortunately current virtual plat-forms are not able to tackle the complexity and heterogeneity of state-of-the-art SoCs. Software emulators, such as the open-source QEMU project, cope quite well in terms of simulation speed and functional accuracy with homogeneous coarse-grained multi-cores.
