Claim 8:
9. An electronic apparatus comprising: a sub-system configured to receive, from a wireless local area network module, incoming data including a plurality of wireless local area network packets according to a plurality of communication methods; and a main system including a processor configured to process the incoming data, the sub-system including an interface circuit configured to acquire a data length of each of the plurality of wireless local area network packets from a header of the each of the plurality of wireless local area network packets, based on a plurality of media access control addresses included in the each of the plurality of wireless local area network packets, identify a communication method of the each of the plurality of wireless local area network packets, and based on the data length and the communication method of the each of the plurality of wireless local area network packets, transfer the each of the plurality of wireless local area network packets to one of a plurality of different storage areas respectively corresponding to the plurality of communication methods, and a sub-processor configured to transfer the each of the plurality of wireless local area network packets from the one of the plurality of different storage areas to the main system, wherein the interface circuit further selects the one of the plurality of different storage areas to which the each of the plurality of wireless local area network packets is transferred, and stores, in a register, at least one media access control address as a filtering target, and when a transmission source address of the each of the plurality of wireless local area network packets is included in the at least one media access control address as the filtering target, discards the each of the plurality of wireless local area network packets.
