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　Model-sim　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.
