METHOD AND APPARATUS FOR CPU VIRTUALIZATION IN MULTICORE EMBEDDED SYSTEM

摘要

The hypervisor of the multi-core embedded system checks the type information of the plurality of virtual machines and the required number of virtual CPUs (Central Processing Units), and based on the type information of the plurality of virtual machines and the required number of virtual CPUs After determining whether the configuration of the virtual system is possible, if it is determined that the configuration of the virtual system is possible, the number of virtual machines required for a Real Time Operating System (RTOS) type virtual machine requiring real-time among the plurality of virtual machines allocating one virtual CPU to each physical CPU, and dynamically allocating the number of virtual CPUs required by the corresponding virtual machine to the remaining physical CPUs to a GPOS (General Purpose Operating System) type virtual machine among the plurality of virtual machines. .
