Classification: CPC H | IPC H

Claim 7:
8. The communication system according to claim 1, wherein the transmitting device comprises:
a coding layer circuit configured for generating the plurality of data units and counting the current transmitted data identification value by itself based on the current data unit;
the FIFO buffer coupled to the coding layer circuit to receive and record the current data unit and the current transmitted data identification value;
a first switching circuit having a first input terminal coupled to the coding layer circuit to receive the current data unit, wherein a second input terminal of the first switching circuit is coupled to a data output terminal of the FIFO buffer, and an output terminal of the first switching circuit is coupled to the communication interface;
a second switching circuit having a first input terminal coupled to the coding layer circuit to receive the current transmitted data identification value, wherein a second input terminal of the second switching circuit is coupled to an identification value output terminal of the FIFO buffer; and
a verification circuit coupled to the output terminal of the first switching circuit, and coupled to an output terminal of the second switching circuit, wherein the verification circuit uses an identification value output by the second switching circuit and a data unit output by the first switching circuit to calculate the transmitted data verification information, and the verification circuit transmits the transmitted data verification information to the receiving device through the communication interface.
