CERN LHC 的 ALICE 使用基于 FPGA 的定制计算机插件卡作为光学探测器读出链路与数据采集 (DAQ) 和高级触发 (HLT) 的 PC 集群之间的接口。 Run1 期间 DAQ 和 HLT 使用的卡已作为独立项目开发，现在面临着类似的问题，主要接口过时，链接速度和处理能力有限。我们开发了一种新的通用卡，可以将读出链升级到更高的链路速率，同时提供与当前架构的向后兼容性。第一个原型可以成功测试并引起其他合作的兴趣。
ALICE at CERN LHC uses custom FPGA-based computer plug-in cards as interface between the optical detector read-out link and the PC clusters of Data Acquisition (DAQ) and High-Level Trigger (HLT). The cards used at DAQ and HLT during Run1 have been developed as independent projects and are now facing similar problems with obsolete major interfaces and limited link speeds and processing capabilities. A new common card has been developed to enable the upgrade of the read-out chain towards higher link rates while providing backward compatibility with the current architecture. First prototypes could be tested successfully and raised interest from other collaborations.
