基于微处理器系统的FPGA在线配置方法

介绍基于SRAM的现场可编程门阵列FPGA器件的在线配置方法,给出了一种采用单片机AT89C51和Flash存储器对A ltera ACEX1K器件进行被动串行在线配置的实用方法。实践表明此方法易于实现,成本较低,可广泛应用于具有微处理器的系统中,完成对FPGA器件的在线配置。

In-Circuit Reconfiguration Scheme for FPGA Based on a Microprocessor System

This paper introduced the In-Circuit Reconfiguration(ICR) schemes for SRAM-Based FPGA.Then it supplied a practical method of PS configuration.In the method microprocessor AT89C51 and Flash memory were used to configure Altera ACEX1K devices.It was proved that the method was easily putted in practice with lower cost and could be also used widely in the system with microprocessor to complete the FPGA's ICR.
