在CERN大型强子对撞机的第三个运行周期中，ALICE实验将在数据采集系统的核心使用一个通用读出单元（CRU）。CRU是基于PCIe40硬件设计的LHCb，是前端、计算系统、触发和定时系统之间的公共接口。475个cru将与3个子系统连接10个不同的子探测器，并将总数据吞吐量从3.5 TB/s降低到635 GB/s。ALICE通用固件框架正在开发中。它支持连续和触发模式的数据采集，时钟，触发和慢速控制交付。本文给出了系统的结构和结果。
For the third running period of the CERN LHC, the ALICE experiment will use a Common Readout Unit (CRU) at the heart of the data acquisition system. The CRU, based on the PCIe40 hardware designed for LHCb, is a common interface between the front-end, the computing system, and the trigger and timing system. The 475 CRUs will interface 10 different sub-detectors with 3 sub-systems and reduce the total data throughput from 3.5 TB/s to 635 GB/s. The ALICE common firmware framework is under development. It supports data taking in continuous and triggered mode, clock, trigger and slow control delivery. In this paper, the architecture and results are presented.
