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 a single chip integrated Bluetooth and FM transceiver and baseband processor are provided. The single chip may comprise a Bluetooth radio, an FM radio, a processor system, and a peripheral transport unit (PTU). FM data may be received and/or transmitted via the FM radio and Bluetooth data may be received and/or transmitted via the Bluetooth radio. The FM radio may receive radio data system (RDS) data. The PTU may support digital and analog interfaces. A processor in the processor system may time-multiplex processing of FM data and processing of Bluetooth data. The single chip may operate in an FM-only, a Bluetooth-only, and an FM-Bluetooth mode. The single chip may reduce power consumption by disabling portions of the Bluetooth radio during FM-only mode and/or disabling analog circuitry when performing digital processing.

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.

摘要： Methods and systems for wireless communication are disclosed and may include sweeping a signal detection frequency one or more times across a plurality of steps in a frequency range. The measured signal strength at each step may be compared to a threshold, and a status may be stored, which may depend on the presence of a measured signal strength above threshold. The detection frequency may be swept utilizing a voltage controlled oscillator, which may be tuned via a control voltage and/or calibration capacitors. Steps may be skipped when a measured signal strength may be greater than the threshold, and may occur after multiple above threshold measurements. The steps may have variable frequency width, and the range may include the Bluetooth band from 2.40 GHz to 2.48 GHz. The frequency may be swept over a subset of the Bluetooth band, and may be swept on a periodic basis.

摘要： Aspects of a method and system for sharing filters between transmit and receive paths in an integrated FM radio are provided. In this regard, a FM radio receive processing path and a FM radio transmit processing path may each be configured to share a filter. Accordingly, one or more switching elements may enable coupling/decoupling the filter to/from the FM radio transmit and FM radio receive processing paths. Furthermore, the switching elements may be programmatically controlled by a processor and/or memory. Additionally, by coupling the filter to the transmit receive paths during alternating time intervals, aspects of the invention may enable simulating simultaneous transmission and reception of FM radio signals utilizing while sharing one or more filters. In various embodiments of the invention, separate filters may be utilized for an in-phase processing path and a quadrature phase processing path.
