【应用笔记】在SOPC Builder中使用DDR/DDR2 SDRAM控制器(Using DDR/DDR2 SDRAM With SOPC Builder)
3.4.0及其以后版本的DDR/DDR2 SDRMA控制器的MegaCore功能模块，支持SOPC Builder，可以在SOPC Builder系统中例化一个DDR/DDR2 SDRMA控制器。
The DDR/DDR2 SDRAM Controller MegaCore® function version 3.4.0
and later supports SOPC Builder, enabling the function to instantiate a
DDR/DDR2 SDRAM Controller inside an SOPC Builder system.
This application note discusses the following topics:
■ Implementing a DDR2 SDRAM Controller within SOPC Builder
■ Incorporating a Nios® II processor and other peripherals
■ Compiling the design and generating the programming file
■ Downloading the design to a board and running sample code on
your design in hardware to test the read and write transactions
