Engineering Contradiction Analysis
1Productivity
If separate processing hardware is used for Bluetooth and FM functions, then processing capability is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines Bluetooth and FM processing functions into a single shared processor. The processor can operate in different modes to handle Bluetooth audio data processing or FM radio data processing, eliminating the need for separate dedicated processing hardware for each function while maintaining full processing capability for both.
Solution Approach 2:
The shared processor is designed with universal functionality to perform both Bluetooth and FM processing tasks. Through mode switching and configurable processing paths, the same hardware resource can adaptively serve multiple communication protocols, reducing overall system complexity while preserving processing productivity.
2Adaptability or versatility
If multiple radios are integrated into a single device, then communication versatility is improved, but power consumption increases
Solution Approach 1:
The patent merges Bluetooth and FM radios into a single integrated device with a shared processor. By consolidating radio functions and processing resources, the system reduces overall power consumption compared to running separate dedicated processing chains for each radio type, while maintaining the ability to support multiple communication protocols simultaneously or alternately.
3Productivity
If separate processors are used for different radio operations, then processing efficiency is improved, but coordination difficulty increases
Solution Approach 1:
The shared processor provides a unified control architecture that can adaptively switch between Bluetooth and FM processing modes. This universal processing platform simplifies coordination by providing a single point of control for managing multiple radio operations, eliminating the need for complex inter-processor communication and synchronization mechanisms while maintaining processing efficiency through mode-specific optimization.

AI summary
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.
