基于ISO标准的磁条卡接口控制器IP的设计

Design of Magnetic Stripe Card Interface Controller IP Based on ISO Standard

重点介绍了基于ISO7810,ISO7811,ISO7812标准的磁条卡接口控制器的一种设计方案,阐述了该控制器的工作原理和该控制器IP核硬件语言模型的建立,以及其在现场可编程逻辑器件上的实现过程,重点介绍了该控制器的结构、内部寄存器的设置以及其数据接收时序图,最后给出关于本磁条卡设计方案的讨论。该方案可以方便地应用于SoC系统设计,但仍需要进一步完善。

A design scheme of magnetic stripe card interface controller based on ISO7810, ISO7811, ISO7812 standard is introduced in this paper. Firstly, the work theory, the HDL modeling of IP core and the implementation of this controller IP using field programmable logic device are briefly introduced. Secondly,the structure,the configure of the inner memory and the scheduling of the controller is described in detail. At last, the discussion about the design is given, the design scheme can be used in SoC,the modification is still needed.
