基于AC104的FPGA远程下载系统设计

Design of Remote FPGA Download System Based on AC104

为满足FPGA配置的灵活性需求,提出一种基于以太网物理层收发器的远程配置方案。该方案以低成本CPLD-EPM570为核心,利用AC104进行物理层传输,通过PS方式完成对FPGA的配置,并内置完善的安全认证策略用于保护FPGA的设计产权。基于该设计方案的FPGA远程下载控制系统已成功运用于某安检设备中。

A new kind of remote configuration architecture based on ethernet is proposed to enhance the flexibility of FPGA configuration, It takes a low cost CPLD,EMP570 as main processor,utilizes AC104 for PHY transmission and configures FPGA via passive serial way. A completely new internal security certification policy is also introduced to protect the intellectual property of FPGA designs, A practical FPGA remote download system based on this design has been applied in some security inspection equipment successfully.
