摘要
在高速、大容量存储的系统设计中,DDR2 SDRAM为设计者提供了高性价比解决方案。在FPGA中实现DDR2 SDRAM控制器,降低了系统功耗并节省空间,缩短开发周期,降低系统开发成本。详细介绍了在Xilinx Spartan-3A系列FPGA中实现DDR2控制器的设计原理,介绍利用MIG软件工具实现控制器设计,并给出硬件测试结果。
With high-speed, large-capacity storage system design, DDR2 SDRAM offers a more costeffective solution for designers. The implementation of DDR2 SDRAM controller with FPGA lowered the power consumption, which also shorten the development cycle and reduced the system development costs. The principle of DDR2 controller implemented in Xilinx Spartan-3A serials FPGA and how to complete it with MIG software tools. The test results are given.
