高精度事例时刻标定插件的设计
The Design of High Precise Event Time Stamping module in BESIII TRIGGER System
【摘要】 介绍了BESⅢ触发系统高精度事例时刻标定插件的设计与实现,该插件可对触发系统产生的好事例判选信号L1*打上精确的时间标签。插件采用GPS授时方案;支持VME总线读写操作及CBLT在线数据读出;所有逻辑功能在FPGA中实现。最后给出了时间标签信息的输出结果,插件的设计达到了预期的设计目标。
【Abstract】 It introduces about the design and implementation of High Precise Event Time Stamping module,which is responsible for stamping the good event pass signal L1*,generated by trigger system.The module is based on GPS timing solution,supported the VME typical read/write cycles and protocol like CBLT for data transfer;all functions are implemented in FPGA.Time Stamping data output is given at the end of the paper.The design achieves the preliminary design object.
