基于Kintex-7 FPGA的DDR3 SDRAM接口应用研究
Application of DDR3 SDRAM interface based on Kintex-7 FPGA
摘要
Abstract
Aiming at the application background of using DDR3 for large-capacity data caching in FPGA,a design scheme of DDR3 SDRAM FIFO interface based on Xilinx Kintex-7 FPGA is presented according to the modularized design method. Based on the analysis of DDR3 user interface characteristics and user interface time sequence,the efficiency of different read-write modes was tested. In combination with the design thought of standard FIFO and characteristics of DDR3 SDRAM control-ler,the traversal state machine is designed to perform the read-write test of the FIFO interface. The interface was verified with the prototype platform. The result demonstrates that the interface has the simple and easy-to-use functions of standard FIFO,and large storage space.关键词
