In this paper, the technology of Bluetooth is analyzed, and a Platform-Based Design （PBD） method tor Bluetoom System-on-Chip （SoC） is proposed. Then, the Bluetooth baseband IP（Intellectual Property） is designed and analyzed. Combined with Hierarchical Power Management （HPM） strategy, a platform-based, low-power and extensible Bluetooth SoC is realized based on the Finite State Machine （FSM） and Clock Gating （CG） technology, and the co-designing and co-verification of HW/SW is implemented based on this platform. A testing method based on SoC platform is proposed for Bluetooth SoC, and the result indicates the system has good performance in developing time, expansibility, power consumption, and transmission. This design results and platform have been applied in standard and enhancing Bluetooth communication system.
