ATLANTIS - a modular, hybrid FPGA/CPU processor for the ATLAS Readout Systems
نویسندگان
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...

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 ...
