摘要
介绍了一种基于软件无线电平台的重构加载方法,通过研究可重构软件无线电硬件体系结构,FPGA可执行设备重构加载原理、协议及Davinci系列处理器高速并行外部存储器接口(EMIF),提出了一种基于DSP+FPGA的重构加载方案,实现了FPGA设备驱动和重构加载软件设计。实验结果表明,软件无线电重构加载方案可高速、准确、可靠地完成波形文件重构加载及不同通信模式的无缝切换。
A new reconfigurable download method based on software define radio（SDR） platform is introduced in this paper.It proposes a new reconfigurable scheme based on DSP ＋ FPGA by studying hardware architectures of reconfigurable SDR,download principles and protocols of executable devices of FPGA as well as the high-speed parallel external memory interface（EMIF） of Davinci series processors,realizing reconfigurable download software design of FPGA device-driver.The result turns out that this scheme can realize the reconfigurable download of wave fires and seamless handover of different communication modes reliably and aecurately at high speeds.
