基于FPGA的SDRAM的控制器实现与性能分析

Realization of FPGA and the analysis performance of SDRAM controller

高速数据采集在通信、雷达、引信编程监测和视频图像处理等系统中具有广泛的应用,系统中大量使用SDRAM实现数据缓存。SDRAM以其体积小、容量大、读写速度快、成本低等特点被广泛应用于工业电子设备中。本文在介绍SDRAM工作原理的基础上,提出了一种基于FPGA控制SDRAM控制器的方法,这种控制器以FPGA为基础,将较难控制的SDRAM转化为用硬件描述语言编写其控制器,从而将复杂问题简单化,进而利用Verilog语言在Quartus9.1的开发环境中进行了设计输入与仿真验证,证明系统的正确性并分析SDRAM如何达到最优性能。

High-speed data acquisition in communication,radar,fuse video monitoring and the programming of image processing system is in a wide range of applications.,Synchronous dynamic random access memory was widely used as data buffer.With its characteristics of small size、large capacity、fast speed and low cost,the SDRAM is widely used in Industrial electronic equipments.Based on the analysis of the SDRAM ＇s work principle,the paper proposes a kind of method of SDRAM controller based on FPGA,and this can make the problem easily,using hardware description language Verilog ,the design and simulation were performed under the environment of quartus9.1 and proves the System’s accuracy and analysis how to achieve optimal performance .
