摘要： Methods for removing complexity from a Bluetooth processor's firmware and placing them in hardware in order to use a simplier processor or to do other tasks in the Bluetooth processor. Assembling and managing communication packets and transmission, providing modulo divides, and allocating memory are typical firmware tasks for a Bluetooth device. By creating circuits that assemble and manage communications packets and transmits, provide modulo divides, and manage Bluetooth device memory a processing burden can be removed from the Bluetooth processor. This lessened processing requirement allows less expensive, e.g. slower, processors to be used, or other functions to be incorporated into the processor's firmware.

摘要： A method and apparatus for channel estimation in a spread spectrum receiver include processing that begins by despreading a received spread spectrum complex baseband sample utilizing a pseudorandom spreading sequence to produce a despread baseband symbol. The processing continues by filtering the despread baseband symbol to attenuate adverse channel effects based on a channel response estimate to produce a filtered despread baseband symbol. The processing then continues by decoding the filtered despread baseband symbol to produce recaptured data. The processing continues by modulating the recaptured data to produce a remodulated symbol. The processing then continues by producing a reconstructed spread spectrum complex baseband sample from the remodulated symbol based on the pseudorandom spreading sequence. The processing then continues by generating the channel response estimate such that a convolution of the channel response estimate with the reconstructed spread spectrum complex baseband sample substantially emulates the received spread spectrum complex baseband sample.

摘要： A method and apparatus for fractional-N synthesis includes processing that begins by generating a 1st feedback frequency from the output frequency based on a fixed divider value. The processing continues by generating a 2nd feedback frequency from the output frequency based on a selectable divider value, a modified fractional value of the divider value, and a modified integer value of the divider value. The processing continues by determining whether the fractional value of the divider value is within a range of fractional values. If so, the 1st feedback frequency is used to produce the output. If the fractional portion of the divider value is not within the range of fractional values, the 2nd feedback frequency is used to produce the output frequency.

摘要： A method and system sharing a Bluetooth processor for FM functions are provided. The single chip may comprise an integrated Bluetooth radio, an integrated FM radio, and processor system. A processor in the processor system may be utilized for Bluetooth and FM data processing and may time multiplex between the Bluetooth and FM data processing based on interrupt signals. The processor may operate in a low power mode based on a clock signal generated from a low power oscillator. When a Bluetooth interrupt signal is received, the processor may enable Bluetooth data processing that may be based on a Bluetooth clock signal. When an FM interrupt signal is received, the processor may enable FM data processing that may be based on an FM clock signal. When data processing is complete, the processor may return to the low power mode operation.

摘要： A method and system for flexible FM tuning are provided and may include tuning to a particular frequency within a range of FM channels based on an IF frequency that includes an integer multiple of the channel spacing between neighboring allocated FM channels within the range of FM channels, offset by at most one-half the channel spacing. The method may further include determining whether the particular frequency comprises an on frequency channel, utilizing a frequency error that is based on the IF frequency. A local oscillator frequency may be selected for the tuning based on the frequency offset. An intermediate frequency (IF) channel may be generated utilizing the particular frequency and the selected local oscillator frequency. The generated IF channel may be between neighboring channels selected from the range of FM channels. The frequency error may be determined for the particular frequency within the range of FM channels.
