为了满足低功耗蓝牙在传输过程中的实时性、准确性和低功耗要求,提出一种应用于低功耗蓝牙链路层的解帧电路。电路基于低功耗蓝牙数据帧的结构和数据处理过程特点,通过状态机控制解帧过程中各个电路模块的工作状态,实现低功耗蓝牙接收设备在数据传输过程中的解帧处理。仿真结果表明,所提电路能够有效地实现对接收的数据帧起止时刻的定位并解析出协议数据单元的具体数据,同时满足低功耗的要求。

To meet the real-time,accuracy,and low-power requirements ofB luetooth Low Energy(BLE)in the transmission process,a frame decoding circuit for the BLE link layer is proposed.The circuit is based on the structure and data processing of theB LE data frame,and controls the working state of each circuit module during the decoding process through a state machine,achieving the frame decoding process of BLE receiving devices during data transmisison.Simulation results show that the circuit can effectivelyo lcate the start and end times of the received data frames,decode the specific data of the protocol data unit,and meet the requirements of low power consumption.
