FAULT DIAGNOSIS APPARATUS AND METHOD FOR SYSTEM-ON-CHIP (SOC) AND SOC IN WHICH FAULT IS CAPABLE OF BEING DIAGNOSED

摘要

A fault diagnosis apparatus and method which can immediately or remotely diagnose faults in a system-on-chip (SoC) mounted on a product, and a system-on-chip in which faults are capable of being diagnosed. The fault diagnosis apparatus for an SoC includes an instruction input unit which inputs fault diagnosis request instruction to the SoC, and an output unit which receives a diagnosis result from the SoC and outputs the diagnosis result, and the SoC receives the fault diagnosis request instruction, diagnoses its own faults, and outputs the diagnosis result to the output unit, thereby immediately or remotely diagnosing faults in the SoC mounted on a product.
