Abstract

A system and a method for operating a plurality of kernels are provided. The system for operating a plurality of kernels includes: N (N is an integer exceeding 1) kernels ported for hardware; and a hypervisor that operates the N kernels so that the N kernels may be simultaneously executed by setting a timer for occurring a timer interrupt for alternately switching the N kernels and by controlling to transfer, if a timer interrupt occurs, a control right from a currently executing kernel to a predetermined next kernel among the N kernels. Therefore, a plurality of kernels can be simultaneously executed using the hypervisor.
