DDR3的IP核的使用相当重要,尤其是对视频处理方面. 下面接收DDR3 的IP 核的生成步骤. 1. 选择DDR IP核的生成路径.名字以及哪种语言之后就可以设置DDR IP 的参数了. 2.选择存储大小,可以选择1G.2G.4G或custom. 操作时钟选择(如果速度等级为8,则就没得选择只有跑到300M). Memory Type 选择on_board_memory,就是焊接在板子上的DDR 芯片.memory data bus size 定义了数据总线的宽度. configuration
DDR PHY interface bit error testing and training is provided for Double Data Rate memory systems. An integrated circuit comprises a bit error test (BERT) controller that provides a bit pattern; and a physical interface having a plurality of byte lane
