Abstract
A communication system and an operation method thereof are provided. The transmitting device transmits the current data unit and the transmitted data verification information to the receiving device through the communication interface, and records the current data unit in an FIFO buffer. The receiving device counts the received data identification value by itself based on the current data unit received from the communication interface. The receiving device uses the received data identification value and the transmitted data verification information to check whether the current data unit received from the communication interface has errors. When the current data unit is in error, the receiving device returns an error flag to the transmitting device so that the transmitting device suspends the transmission of the new data unit, and transmits the buffered data unit recorded in the FIFO buffer to the receiving device through the communication interface.
