An　embedded　LCD　display　interface　in　a　grating　measurement　chip　is　implemented　in　this　paper　based　on　Verilog　HDL,　which　includes　four　modules　in　the　circuit,　MCU,　CDU,　I/O　and　a　synchronous　FIFO.　SMG12864C　chip　is　used　as　the　LCD　driver　module　in　this　paper.　Verilog　HDL　is　employed　in　the　interface　circuit　describing　the　design,　software　Modelsim　accomplishes　the　function　simulation,　and　the　circuit　is　synthesized　by　Synplify　tool.　After　post-simulation　and　verification　on　the　Xilinx　VirtexII　family　device,　the　timing　analysis　indicates　that　the　designed　circuit.　meets　the　requirement　of　display　interface.　Besides,　the　circuit　also　possesses　a　good　flexibility,　meaning　that　it　is　easy　to　adapt　to　other　LCD　driver　modules　by　simply　modifying　the　timing　constraints　in　MCU　module.
