SPI在TD-SCDMA/GSM双模移动开发平台中的应用

Application of SPI in TD-SCDMA/GSM dual-mode mobile development platform

本文简要介绍了基于软件无线电技术的新型TD-SCDMA/GSM双模移动终端开发平台,该平台中的主要模块及FPGA作为协处理器在该平台中实现的功能。根据SPI的协议标准和在该平台中的通信协议要求,介绍了SPI在双模开发平台中的实现应用方法。设计中采用Verilog HDL语言并在Xilinx公司的Virtex-Ⅱ系列FPGA芯片内成功模拟出一个SPI接口,其仿真测试和实际应用均完全符合此双模平台通信的要求。

This paper introduces briefly a new type of TD-SCDMA/GSM dual-mode mobile terminal development platform of a software-based radio technology, the main module of this platform and the FPGA as a coprocessor to achieve the function. According to the SPI protocol and communication command, the method of SPI in the dual-mode development platform in the realization of the application is introduced. A SPI interface is simulated successfully by Verilog HDL language used in Xilinx＇s Virtex-Ⅱ series FPGA chip, its simulation and practical application accord with the communication command of this platform entirely.
