IC卡又称智能卡,是用于个人识别信息及用户与系统之间数据管理的集成电路芯片模块。依据通信机具体的通信协议,在基于FPGA技术和VHDL语言的基础上,运用了QuartusⅡ工具,将工程模块化设计,实现了外界与IC卡的通信。最后附上了IC卡的开机自检指令响应,验证了设计的正确性。文中涉及数据传输的串并/并串转换、先进先出堆栈(FIFO)、数据的异步半双工传输以及状态机原理,对EDA设计具有一定的实用价值。
IC card, also known as smart card, is an integrated circuit chip module for personal identification information and data management between users and systems. Based on the communication protocol of the communication device, based on the FPGA technology and VHDL language, the Quartus II tool was used to modularize the project and realize the communication between the outside and the IC card. Finally attached the IC card POST command response, verify the correctness of the design. The article deals with the serial / parallel serial conversion of data transmission, first-in-first-out stack (FIFO), asynchronous half-duplex transmission of data and state machine principle, which have certain practical value for EDA design.
