FPGA内嵌ROM表对DRAM控制的实现

FPGA Embedded ROM Table to Control DRAM in Ship Hardware Design

指挥控制系统是现代军舰的灵魂,而肩负专用功能的电子模块组成了指挥控制系统的"躯体"。各种存储器件是存储数据的载体,对存储器件的控制和操作成为专用电子模块设计的重要组成部分。动态存储器(DRAM)是重要的存储器件,现场可编程门阵列(FPGA)在计算机硬件设计领域的应用也十分广泛。重点阐述了应用FPGA实现对DRAM的复杂控制,并由此提出了一种运用ROM表的简便方法,工程实践证明该方法具有广泛的通用性和较强的实用性。

Command and control（ C^2） system is modern warship＇s soul, and the sepecial electronic modules make up the C^2 system. Various storage chips are data storage media,and means to control and operate the storage chips is an important part in hardware design. DRAM is an important memory device, the application of FPGA is quite extensive in the area of hardware design. This paper is fl^cused on the application of FPGA which can realize the complex control to the DRAM. The author presented a simple way to use ROM table, which has been proven in the engineering practice.
