一种可靠的FPGA动态配置方法及实现

A Reliable Dynamic Configuration and Implementation of FPGA

现场可编程逻辑门阵列(FPGA)在通信系统中的应用越来越广泛。随着通信系统的复杂化和功能多样化,很多系统需要在不同时刻实现不同的功能,多数场合需要FPGA能够支持在线动态配置;在某些安全领域,需要对FPGA程序进行加密存储、动态升级。这里根据应用趋势提出了一种基于CPU+CPLD的可靠的FPGA动态加载方法。该方法具有灵活、安全、可靠的特点,在通信电子领域具有一定的参考价值。

FPGA is widely applied in communication system.Along with complication and the function diversification of communication system,many systems are required to implement different functions at different points of time,and in many occasions,FPGA is demanded to support the on-line dynamic configuration.Also in some security fields,it is required to implement encrypted storage and dynamic up gradation of FPGA program.The article proposes a reliable dynamic configuration method based on CPU and CPLD,which has the features of flexible configuration,security and reliability,and thus could be of certain reference value in electronic communication field.
