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.
