LHC光纤数据链路传输中LOCic系统编解码延时测量
在高速数据传输中,数据传输延时是表征编解码系统性能的重要参数,特别是在欧洲核子中心LHC（大型强子对撞机）ATLAS（超环面仪器实验）探测器读出系统里尤为重要.针对将用于LHC ATLAS实验升级中的LOCic（线码在芯片专用集成电路）线性编码系统的FPGA实现给出了其延时参数测量的设计方法和实现过程.准确地测得了延时大小,说明了LOCic线性编码的低延时特性,为用于ATLAS实验升级中对该线性编码系统性能标定提供了依据....

Especially, in the CERN＇s the large hadron collider（LHC） ATLAS detector readout sys- tem shorter latency is particularly important. As for the LOCic （line of code in application-specific integrated circuit chip） which will be applied to the LHC ATLAS experiment upgrade, the FPGA firmware of the linear coding system has given the designing methods and the implementation process for the time delay parameters test. According to this way, it has measured the size of de- lay accurately, and has illustrated the low-latency characteristics of linear code of the |
