双数据速率(DDR)同步动态随机访问存储器(SDRAM)控制器是一种通用存储器控制器,与行业标准接口DDR2 SDRAM。内存控制器提供了一个通用的命令interface to the user's application. This interface reduces the effort to integrate the module with the remainder of the application and minimizes the need to deal with the DDR2 SDRAM command interface. The timing parameters for the memory can be set through the signals that are input to the core as part of the configuration interface. This enables switching between different memory devices and modification of timing parameters to suit the application using the same netlist.
