摘　　要：为了实现对基于FSK调制的低频标签的准确读写,设计一种功耗低、精确度高、频率范围自适应的逻辑系统。借助自顶向下的设计方法,并引入内部寄存器指令控制集对逻辑结构进行分块实现,利用软件仿真以及硬件电路验证设计的正确性,内部寄存器指令控制集可有效协调各模块之间数据流信息与控制流信息的交换,并对系统进行实时状态检测。仿真结果表明,逻辑结构实现了对基于FSK低频标签的准确读写,大大降低了功耗,同时证明了逻辑结构在实际电路中应用的可靠性。In order to realize accurate reading and writing of low frequency tags based on FSK modulation,a logic system with low power consumption,high precision and frequency range is designed.By means of the top-down design method and the internal register instruction control set is introduced to block the logical structure,and software simulation and hardware circuit are used to verify the correctness of the design,the internal register instruction control set can effectively coordinate between the modules data stream information and control flow information exchange,and the system status can detected in real-time.The results show that logical structure realizes accurate reading and writing of FSK low frequency tags,and the power consumption is obviously optimized,and the reliability of logical structure in the actual circuit is proved.
