论文摘要
建造了一个新的MUON到中央触发处理器接口（MUCTPI），作为ATLAS Level-1触发系统升级的一部分，用于CERN大型强子对撞机的下一次运行。 MUCTPI具有208个高速光学串行链接，用于从MUON触发探测器接收若干候选者。三个高端FPGA用于实时处理MUON候选者，将触发信息发送到触发系统的其他部分，并将摘要信息发送到数据采集和监视系统。片上系统（SOC）用于控制，配置和监视MUCTPI的操作。 SOC由FPGA部分和处理器系统组成。 FPGA部分提供了与处理FPGA的通信，而处理器系统运行的软件可以与Atlas实验的Run-Control系统通信。在本文中，我们将描述我们在SOC上运行Centos Linux的经验。正在使用跨编译以及用于构建Atlas触发器和数据采集（TDAQ）软件的现有框架，以允许直接在SOC上部署TDAQ软件。
A new Muon-to-Central-Trigger Processor Interface (MUCTPI) was built as part of the upgrade of the ATLAS Level-1 trigger system for the next Run of the Large Hadron Collider at CERN. The MUCTPI has 208 high-speed optical serial links for receiving muon candidates from the muon trigger detectors. Three high-end FPGAs are used for real-time processing of the muon candidates, for sending trigger information to other parts of the trigger system, and for sending summary information to the data acquisition and monitoring system. A System-on-Chip (SoC) is used for the control, configuration and monitoring of the hardware and the operation of the MUCTPI. The SoC consists of an FPGA part and a processor system. The FPGA part provides communication with the processing FPGAs, while the processor system runs software for communication with the run-control system of the ATLAS experiment. In this paper we will describe our experience with running CentOS Linux on the SoC. Cross-compilation together with the existing framework for building of the ATLAS trigger and data acquisition (TDAQ) software is being used in order to allow the deployment of the TDAQ software directly on the SoC.
