摘　　要：为了完成并行数据格式DSP和串行数据格式SIM卡间的通信,基于ISO/IEC7816-3串行通信协议,在FPGA平台上实现了他们之间的通信。FPGA完成了从DSP数据到SIM卡的数据并/串转换与写入,SIM接收到数据信息后会返回信息,FPGA完成返回数据的串/并转换以及回传到DSP。此方案不仅解决了DSP与SIM卡间串行通信问题而且与软件实现方案相比,大大减少了通信时间。To finish communication between DSP with the parallel data format and SIM card with the serial data format, the paper implements the communication between them based on ISO/IEC7816 - 3 serial communication protocol on FPGA hardware platform. FPGA finished data conversion from parallel data in DSP to serial data in SIM. The SIM returns a signal when it receives digital signal. FPGA converts the signal to serial data and inputs DSP. It will not only solve the problem of serial communication between DSP and SIM but also need less time than the implementation of communication with software.
