Abstract: A system on chip includes a memory, a main processor that runs an operating system, and first Intellectual Properties (IPs) that perform respective processing operations. The main processor operates to copy target firmware to the memory using a firmware loader, using a hypervisor, block access of the main processor and the first IPs to the target firmware before verification of the target firmware, and using the hypervisor, grant access to the target firmware by a target IP among the first IPs that corresponds to the target firmware after the verification of the target firmware.
