In this paper, we present a technique for optimizing the simulation speed of the QEMU and SystemC-based virtual platform.Most of the optimization methods for conventional instruction set simulator based virtual platforms focus on accelerating the simulator kernel. However, the bottleneck that affects ...
terms of SystemC modules, all OVP components that should be integrated in the target platform. To avoid such drawbacks, and provide an easy way to port SystemC models from a QEMU-based to an OVP-based virtual platform and vice versa, this paper presents a common co-simulation approach that...
A common architecture for co-simulation of SystemC models in QEMU and OVP virtual platforms Several approaches have been proposed for cosimulation between QEMU and SystemC. On the contrary, no paper addresses integration between Open Virtual Platform (OVP) and SystemC. Indeed, OVP models and the...
