RISC-V Summit

In embedded system development, several technical issues need to be solved to facilitate the transition from another architecture to RISC-V. For example, in existing embedded devices, there are products with multiple OSs, including RTOS. In such products, hardware virtualization is used to run General Purpose OS(GPOS) and RTOS to guarantee real-time performance and use GPOS software assets. However, some OSs (especially RTOS) are not intended to run on virtual machines. Therefore, we are researching a mechanism that enables all RTOSs to run even on a RISC-V virtual machine. In this talk, we will provide strategies for running the RTOS on virtual machines and the issues to be solved for its practical use.
