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.
