Application processor, automotive electronic processor, and computing device including application processor

An automotive electronic processor comprising:

• a central processing unit;
• a root complex that communicates with an external device under control of the central processing unit and to generate an interrupt when an operation state changes;
• and
• an interrupt aggregation and debug unit that performs debugging on a component associated with the interrupt depending on the interrupt, wherein:
• the external device includes a brake controller, a steering controller, a power train controller, a lamp controller, an image controller, an engine controller, a battery controller, a wiper controller, a safety controller, or a display controller, and
• the interrupt aggregation and debug unit clears the interrupt without sending the interrupt to the central processing unit.

A computing device comprising:

• an application processor and a device that communicate with each other, wherein:
• the application processor includes:
• a central processing unit;
• a root complex that communicates with the device;
• a bus that connects the central processing unit and the root complex;
• and
• an interrupt aggregation and debug unit that communicates with the root complex through the bus,
• the device includes an end point interface that communicates with the root complex, and
• the interrupt aggregation and debug unit:
• performs debugging of the root complex and the end point interface depending on a state change interrupt indicating a change of a state of the root complex;
• increases an interrupt count in response to a data interrupt occurring while the root complex is communicating with the end point interface;
• and
• sends an interrupt to the central processing unit when the interrupt count reaches a threshold value.
