| Research Abstract |
SafeG-MP is a virtualization environment that allows a real-time operating system (RTOS) to run concurrently with a general-purpose operating (GPOS) on a multi-core embedded system. SafeG-MP schedules the workload of each core between both OSs independently. When both Oss are ready to run on a certain core, the RTOS is executed with higher priority. Unfortunately, such scheduling algorithm has performance issues on the GPOS: an increased synchronization delay, and a load imbalance among cores.We propose a technique to address both issues. We implemented and evaluated it on a physical platform, confirming its effectiveness at mitigating the GPOS performance loss.
