The Design of DDR-SDRAM Controller Based on Spartan3

Abstract:

The controller of DDR-SDRAM was designed with Spartan 3 of Xilinx.The design of the controller is made of the initialized program for power on and read/write control program.The design that uses state machine designing method was realized by VHDL language .The design was verified by software simulation of modelsim first,then it was verified by the PCB.The result of test indicates that the design of the controller for DDR-SDRAM met the demand of design and realized the control of the read/write DDR-SDRAM.
