介绍了一种基于现场可编程门阵列的嵌入式高能工业CT同步控制系统。该系统将现场可编程门阵列作为系统时序控制的核心，其内部集成了UART、指令解码、LCD显示、EEPROM读写和同步时序产生等模块。系统采用有限状态机设计了指令解码模块，具有良好的可扩展性。同时，设计了基于查找表结构的频率计数值产生模块，提高了系统处理速度，减少了逻辑资源的占用。最后，采用VC++设计了控制软件，并通过实验得到了清晰的图像数据。

An embedded synchronization system based on FPGA for high energy industry CT is introduced. FPGA is the main unit of the system, including UART, decoding module, LCD module, reading/writing EEPROM module, synchronization timing module, and so on. Decoding module is designed with finite state machine, and has good expansibility. Lookup table is adopted in the counter of frequency module to increase processing speed and decrease resource consumption. The control software is designed by VC++, and high quality images have been acquired through experiments.
