FPGA在TD-SCDMA通用开发平台中的应用

摘要

FPGA plays a more and more important role in modern digital circuit design because of its excellent performances, such as sort cycle, low cost, small risk and flexible configuration etc, which can realize more complex functions in a short time.In the TD- SCDMA mobile telephone development platform based on software defined radio technology, the digital signal processing operation, in which a lot of data need to be dealt with rapidly, was competed and relevant data interfaces were realized with DSP taken as a main processor and FPGA as an assistant processar.On the platform, TD-SCDMA protocol softwares, physical layer softwares, mobile telephone chips, mobile terminals and other relevant products can be tested with different softwares.%随着FPGA容量、功能以及可靠性的不断提高,采用FPGA设计数字电路已经成为数字电路系统领域的主要设计方式.在以DSP为主处理器,FPGA为协处理器,基于"软件无线电"技术的TD-SCDMA通用开发平台中,成功地采用FPGA完成一系列数据量大、重复性强、速度要求高的数字信号处理运算和相关数据接口.在这种平台中采用不同的软件,便可以对TD-SCDMA协议栈软件、物理层软件、手机芯片和移动终端等相关产品进行测试验证,具有很好的市场前景.
