Abstract
A die-to-die communication system and an operation method thereof are provided. The die-to-die communication system includes a transmitting device disposed at a first die and a receiving device disposed at a second die, wherein the first die and second die are disposed in a same integrated circuit package. The receiving device is coupled to the transmitting device via a communication interface. The transmitting device transmits a data unit stream to a data channel in the communication interface. The receiving device receives the data unit stream from the data channel in the communication interface. The receiving device returns transmission management information to the transmitting device via a feedback channel different from the data channel in the communication interface. In various embodiments, the transmission management information includes flow control information and/or error replay information. Based on the transmission management information, the transmitting device manages the data unit stream in the data channel.
