Communication controller, communication method, and system on a chip

Abstract

An optimized communication technique is provided. A communication controller has a retransmission list and a destination control logic circuit. The retransmission list records an identification number of a communication transaction that failed to transmit from a source module to a destination module. The destination control logic circuit manages the retransmission list. When a tracker is released from a queue of the destination module, the destination control logic circuit requests the source module to retransmit the communication transaction to the destination module according to the identification number recorded in the retransmission list.

Dependencies are inferred from the claim text.
