Integrated circuit device, system-on-chip including the same, and packet processing method

An integrated circuit device comprising:

• processing circuitry configured to function as an intellectual property (IP) to generate a plurality of response packets by,
• determining a scheduling policy based on a request type associated with a plurality of request packets, when the plurality of request packets are input from the outside,
• distributing the plurality of request packets to a plurality of processing elements according to the scheduling policy, the plurality of processing elements configured to generate the plurality of response packets such that a header of each of the plurality of response packets includes an identifier (PE ID) of a respective one of the plurality of processing elements which processed a respective one of the plurality of request packets, and
• aggregating the plurality of response packets according to the scheduling policy such that the plurality of response packets are selectively reordered based on the PE ID to match an order that the plurality of request packets were distributed to the plurality of processing elements, in response to the request type being a write request.

A packet processing method comprising:

• determining a scheduling policy based on a request type associated with a plurality of request packets, when the plurality of request packets are input;
• distributing the plurality of request packets to a plurality of processing elements according to the scheduling policy;
• processing the plurality of request packets through the plurality of processing elements to generate a plurality of response packets such that a header of each of the plurality of response packets includes an identifier (PE ID) of a respective one of the plurality of processing elements which processed a respective one of the plurality of request packets;
• and
• aggregating the plurality of response packets according to the scheduling policy such that the plurality of response packets are selectively reordered based on the PE ID to match an order that the distributing distributed the plurality of request packets to the plurality of processing elements, in response to the request type being a write request.
