QuantumLeap - Virtual Platform Simulation Acceleration

Overview

QuantumLeap is a parallel simulation performance accelerator that leverages a new synchronization algorithm to provide the fastest virtual platform software execution speed available. The execution performance of this new technology has been measured on average at 15 times faster than the nearest commercial solution using standard benchmarks. Many current System-on-Chip (SoC) hardware platforms, for example mobile and server devices, incorporate multi-core embedded processors coupled with hardware accelerators, all executing in parallel. The performance of existing, single-threaded virtual platform simulators does not adequately scale for these SoCs, creating a barrier to efficient virtual platform-based software development. QuantumLeap eliminates this barrier by allocating the simulated cores across all the processors in a host machine. By ensuring the efficient synchronization of these cores, near linear scaling of the simulation across the multiple host processors has been observed, with the impact of inter-core communication kept to a minimum. Furthermore, QuantumLeap provides a transparent use model, with no change required to the software-under-test, the virtual platform models or the development environment, while ensuring fully deterministic simulation execution. The execution performance of this new technology has been measured on average at 15 times faster than the nearest commercial solution using standard benchmarks. Simulation performance of great than 16 Billion Instructions-Per-Second has been observed for a virtual platform using an OVP model of a multi-core ARM Cortex-A9 running on a standard 3.4 GHz quad core host PC.
