چکیده

ATLANTIS realizes a hybrid architecture comprising an industry standard PC platform plus di erent FPGA based modules for high-performance I/O (AIB) and computing (ACB). It is a exible and modular system which can be the platform for several applications. CompactPCI provides the basic communication mechanism, enhanced by a private bus. The system can be tailored to a wide range of applications by selecting an appropriate combination of modules. Acceleration of computing intensive Atlas level-2-trigger tasks has been demonstrated with an ACB based system. The Atlas RoD and RoB systems will pro t from the exible and highly e cient AIB I/O architecture. Various highspeed interface modules (e.g., S-Link / M-Link) are supported, allowing up to 28 links per CompactPCI crate.

An Overview of the Mannheim ROB Complex Hardware

2. Introduction In conventional computers an algorithm is executed by a CPU that processes a sequence of standard instructions. Contrary an FPGA processor allows the implementation of an algorithm directly in hardware. An FPGA chip contains a high number of simple logical elements which can be “wired” by software by downloading a configuration file. Thus the hardware of the FPGA processor – the...

Prototype Readout Module for the ATLAS Level-1 Calorimeter Trigger Processors

The level-1 calorimeter trigger consists of three subsystems, namely the Preprocessor, electron/photon and tau/hadron Cluster Processor (CP), and Jet/Energy-sum Processor (JEP). The CP and JEP will receive digitised calorimeter trigger-tower data from the Preprocessor and will provide trigger multiplicity information to the Central Trigger Processor and region-of-interest (RoI) information for ...

Evaluation of an FPGA and PCI bus based readout buffer for the Atlas experiment

This dissertation evaluates a readout buffer system for the ATLAS detector trigger and data acquisition system. ATLAS is a high energy physics experiment at the large hadron collider (LHC) with the aim to reach new frontiers in the investigation of the structure of matter. The high precision ATLAS detector produces a huge amount of data, 40 TByte/s, which is reduced by a three-level trigger sys...
