光纤传感系统SDRAM控制器的FPGA设计与实现OA北大核心CSCD
Design and realization of the SDRAM controller based on FPGA used in fiber sensor system
根据SDRAM的工作原理和接口时序特点,提出了一种基于FPGA的SDRAM控制器实现方法.采用VHDL在MODELSIM环境进行设计与仿真,较好地实现了各种工作状态的转换.在Xilinx公司的器件上利用CHIPSCOPE进行验证,实验结果表明,SDRAM能够很好地完成读写操作.
Aimed at the working principle and the characteristics of time sequence, SDRAM controller implementation method was put forward based on FPGA. Design and emulator the program using the VHDL langue based on the modelsim. The state machine in program runs well. The program is proved on xilinx device using the chipscope. The result indicates that FPGA can write and read data from SDRAM.
