  • Publication number: 20100107149
    Abstract: A patching device and method thereof for patching a firmware function by a patch function. When a fetch address from a processor does not correspond to the firmware function, the patching device outputs an instruction of the fetch address to respond to the processor. When the fetch address corresponds to the replaced firmware function, the patching device outputs an artificial instruction to respond to the processor. The artificial instruction is one of series of machine codes corresponding to a plurality of patch intermediary instructions utilized to direct the processor to jump to the beginning address of the patch function.

  • Publication number: 20090247217
    Abstract: The invention provides an apparatus capable of wireless communications. In one embodiment, the apparatus comprises a packet traffic arbitration (PTA) module and a first wireless transceiving module, and the first wireless transceiving module is connected to the PTA module via a wire. The first wireless transceiving module sends a first request for performing a first signal transceiving to the PTA module via the wire, receives a first response to the first request via the wire, and performs the first signal transceiving when the first response indicates that the first request has been granted by the PTA module.

  • Publication number: 20090245279
    Abstract: The invention provides a method for operating an apparatus capable of Bluetooth and Wireless Local Area Network (WLAN)/WiMAX communications. In one embodiment, the apparatus comprises a Bluetooth module, and a WLAN/WiMAX unit comprising a packet traffic arbitration (PTA) module, and a WLAN/WiMAX module. The Bluetooth module sends a request for Bluetooth signal transceiving to be performed in a Bluetooth time slot to the WLAN/WiMAX unit, wherein the request comprises a length information about length of a transceiving time period for Bluetooth signal transceiving. The Bluetooth module then performs an Bluetooth signal transceiving during the transceiving time period of the Bluetooth time slot after the WLAN/WiMAX unit grants the request. The WLAN/WiMAX unit then performs an WLAN/WiMAX signal transceiveing during a residual time period of the Bluetooth time slot in response to the length information.

  • Publication number: 20090180460
    Abstract: An embodiment of a method for link management in a scatternet, performed by a wireless communication device, is provided. The wireless communication device simultaneously establishes a synchronization link in a first piconet, and an asynchronization link in a second piconet. The embodiment of the method contains the following steps. At least one time interval originally utilized for packet transmissions in the synchronization link is sacrificed. During the sacrificed time interval, the asynchronization link is switched to for a time period to maintain connection between the wireless communication device and a peer device operating with the asynchronization link.
