A recently granted patent (Publication Number: US11924684B2) discloses an electronic apparatus with a sub-system and a main system designed to efficiently process incoming data from a wireless local area network module. The sub-system includes an interface circuit that acquires data length and communication method information from incoming wireless local area network packets, allowing for the transfer of packets to specific storage areas based on these parameters. A sub-processor then transfers the packets to the main system for further processing. Additionally, the interface circuit includes a selector circuit to determine the appropriate storage area for each packet based on its communication method.

Furthermore, the patent details a method for controlling the electronic apparatus, performed by the sub-system, which involves receiving incoming data, identifying communication methods, transferring packets to designated storage areas, and ultimately sending the data to the main system for processing. The method also includes filtering capabilities based on media access control addresses, allowing for the discarding of packets from specific transmission sources. This innovative approach to managing wireless local area network data showcases a sophisticated system that optimizes data processing and storage within electronic devices, potentially enhancing overall performance and efficiency in various applications such as image forming processes.
