针对软件无线系统对信号处理模块提出的高效、可复用等要求,设计并实现了基于DSP和FPGA的可重构信号处理平台。平台采用分层式架构,通过硬件资源隔离与模块化设计,完成对波形重构的灵活配置与高效管理。在DSP端执行波形软件加载,其中使用Slave SelectMap方式加载FPGA配置文件,并结合EDMA进行数据搬移,加快了系统重构过程。测试结果表明,该设计方案具备良好的实时性、稳定性与扩展性,为软件无线系统中的信号处理平台设计提供了一定的参考。
Abstract
In view of the requirement that efficiency and reusability for signal processing modules in software-defined radio (SDR) systems, this paper designs and implements a reconfigurable signal processing platform based on DSP and FPGA. The platform adopts a layered architecture, enabling flexible waveform configuration and efficient management through hardware resource isolation and modular design. Waveform software loading is performed on the DSP side, where the FPGA configuration file is loaded using the Slave SelectMap method, combined with EDMA (Enhanced Direct Memory Access) based data transfer to accelerate the system reconfiguration process. Test results demonstrate that the proposed design achieves excellent real-time performance, stability, and scalability, providing valuable insights for the design of signal processing platforms in SDR systems.
