摘　　要：物联网(internet of things,IoT)是目前通信技术行业发展的重要趋势,为世界的信息产业带来了第三次信息浪潮。在物联网发展中,射频识别(radio frequency identification,RFID)是其核心技术,RFID技术的市场需求和发展前景是不可估量的。在RFID技术中,核心部件是阅读器,而运用SoC设计方法实现了单芯片系统该部件的主流实现方案。文中采用开源MC8051软核,实现了基于ISO/IEC 18000-6C协议的RFID阅读器SOC系统的软硬件协同设计。其中,软件部分完成系统的控制以及协议命令的处理,而硬件部分实现了包括数据发送和接收的基带通信链路。在设计的SOC中,MC8051处理器还连接了外部RAM,并通过WISHBONE总线与自定义的通信链路模块接口互连。最终,系统在Modelsim下进行了软硬件的仿真验证。IoT(internet of things)is an important trend in current communication technology industry,which is bringing the third information waves to the world’s information industry.In the development of IoT,RFID(radio frequency identification)technology is the core.The market demand and development prospect of RFID technology is immeasurable.In the RFID technology,the core part is the reader,and their mainstream implementation is single chip design with the SoC technology.By using the open source MC8051 soft core,we realize the software and hardware co-design of an ISO/IEC 18000-6C protocol complied RFID reader SOC system.The software part takes charge of the system control and the protocol command processing,while the hardware part realizes the physical layer of baseband data communication link,including data sending and receiving.In the designed SOC system,the MC8051 processor connects to an external RAM,and also connects to the self-designed communication hardware through the WISHBONE bus.Finally,the system’s software and hardware have been verified under Modelsim environment.
