Abstract: A system on chip comprises a first core cluster including a plurality of cores and executing a first virtual machine including a first debug client, and a second core cluster including a plurality of cores and executing a second virtual machine including a second debug client. A first core of the first core cluster and a second core of the second cluster execute a hypervisor at a first exception level and detect unusual operation cores in each cluster. The first core and second core execute the debug server at the first exception level and call the debug clients. The first core and second core execute the debug clients at a second exception level and output stack information of the unusual operation cores.
