AbstractThe ATLAS Collaboration has developed a functional model of a Data Acquisition and Trigger architecture. The architecture under study foresees a 3 Level trigger and a highly parallel and scalable Data Acquisition system. In order to cope with the high prompt trigger rate (up to 100 kHz) and huge data throughput (150 GByte/s from the FE electronics) a mechanism has been introduced to reduce by two order of magnitude the data required by the Level 2, which provides a high rejection before full Event Building.
This paper describes the requirements of the ATLAS experiment in terms of trigger rates and data throughputs, and the main aspects of the hardware and software architecture presently under study.
