After the overall structure of SOC was described, hardware function, software function and interface of hardware/soft-ware were introduced. Some key techniques were explained in detail, such as regulator design method based on synchronism or asynchronism, transmit control method of virtual link based on mealy finite state machine. Finally, AFDX protocol chip was validat-ed on EP1S40, results of which show that this chip can satisfy AFDX protocol.
