基于反熔丝型FPGA的可重构设计

Design of Reconfigurable Anti Fused FPGA

阐述一种基于反熔丝型FPGA实现载荷内部信号处理单机软件重构方案。反熔丝型FPGA外扩RS422接口接收主控设备的命令,LVDS接口接收重构数据,控制NorFlash读写,从而实现对软件重构。该设计已应用于星载合成孔径雷达信号处理单机,实现在轨的软件重构。

This paper describes a single machine software reconstruction scheme for load internal signal processing based on an anti fuse FPGA.Based on the anti fuse FPGA external expansion RS422 interface,it receives commands from the main control device,while the LVDS interface receives reconstructed data and controls NorFlash read and write,achieving software reconstruction.This design has been applied to a single machine for satellite borne synthetic aperture radar signal processing,achieving software reconstruction in orbit.
