SDRAM内存条控制器的设计与实现

Implementation and Design of SDRAM MODULES Controller

SDRAM内存条具有速度高、容量大、接口标准、扩展方便等优点,但是它在计算机内部有专门的控制器CPU控制其工作,为了能在计算机以外的其它工程场合加以应用,就必须设计一个SDRAM内存条控制器。文中提出了层次式的设计方法,并用该方法设计了一种基于CPLD的SDRAM内存条控制器,从而解决了内存条的工程应用问题。

SDRAM MODULES has lots of advantages, for instance,- high speed, mass storages, standard interface, easy extending and so on.However, it has expert controller CPU which controls its work in computer, we must design a controller to control SDRAM MODULES so that we can use it in other domains besides in computer. A method of ＂Hierarchy＂is put forward, a SDRAM MODULES controller is designed based on CPLD,and the application of SDRAM MODULES in engineering is also solved in the paper.
