  • Patent number: 8014723
    Abstract: A wireless transceiver includes a first integrated circuit and a second integrated circuit. The first integrated circuit includes a memory module that stores a plurality of operational instructions for implementing a plurality of protocol layers of a wireless protocol, a processing module that executes the plurality of operational instructions, and a first interface module. The second integrated circuit includes a second interface module that couples data to and from the first interface module, an RF transceiver that modulates a first baseband signal to produce a transmitted RF signal, and that demodulates a received RF signal to produce a second baseband signal, and a baseband module that generates the first baseband signal based on data received from the first interface module via the second interface module, and that generates data based on the second baseband signal to send to the first interface module via the second interface module.

  • Patent number: 5887046
    Abstract: A method of accumulating and maintaining the accumulated data comprises steps of maintaining an intermediate count in a first memory device (12), reading a plurality of count values from a second memory device (14), determining a greatest count value of a subset of the plurality of count values which satisfy at least one criterion, and determining an updated count based upon the intermediate count and the greatest count value. The at least one criterion includes a criterion that the greatest count value differs from a second greatest count value of the subset of the plurality of count values by at most a predetermined difference greater than one. A system and a device to perform the method are detailed.
