基于现场可编程门阵列的高能工业CT同步系统设计

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。

Design of embedded synchronization system for high energy industry CT based on FPGA

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.
