Abstract
A system on chip (SoC) is provided. The system on chip includes a multiprocessor that includes multiple processors, a debugging controller that includes a debug port and retention logic configured to store an authentication result of a secure joint test action group system, and a power management unit configured to manage power supplied to the multiprocessor and the debugging controller. The power management unit changes the debug port and the retention logic into an alive power domain in response to a debugging request signal.
