SDRAM controller designed for real-time display system of large-array CCD image

After analyzing the principle of SDRAM,a Synchronous Dynamic Random Access Memory(SDRAM) controller used in large-array CCD image real-time display system was designed with parameterization design concept.It was implemented by VHDL hardware description language and had a simple interface.Then the SDRAM controller was successfully used in real-time display system of large-array CCD image and worked very well.
