摘　　要：设计了一种基于Zynq-7000芯片的高速实时自适应均衡系统,该系统采用GAL-NLMS算法。芯片的PL部分实现了35阶的GAL算法模块和AXI-Stream IP设计,PS实现了基于Linux的驱动程序设计,基于Qt的应用程序设计和NLMS算法模块,并详细介绍了系统的开发流程。PL与PS内部通信速率达到了5.32 Gbit/s,外部最高输入速率达到175 Mbit/s,误差百分比小于3%。对当前和今后的高速通信具有很强的实用价值。A high speed real time adaptive equalization system based on Zynq-7000 chip is designed by using GAL-NLMS algorithm. GAL algorithm module of 35 order and AXI-Stream IP module is realized in the PL part of chip. The design based on the Linux driver,application program design based on Qt and NLMS algorithm module are realized in the PS part of chip. The system development process is introduced in detail. The internal communication rate of PL and PS achieves 5.32 GbiCs and the highest rate of external input reaehs 175 Mbit/s and percentage of error is less than 3%. It is practical and of great value for the current and future high-speed communication.
