CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishIn this paper we describe DPFPA (Double Precision Floating Point Accelerator), a FPGA-based coprocessor interfaced to the CPU through standard bus connections; it is conceived to accelerate double precision floating point operations, featuring two double precision floating point units, a pipelined adder and a pipelined multiplier with a suitable number of stages. We tested its performance by implementing a Montecarlo-Metropolis simulation of a dipolar system, using a proper software development environment designed and realized in our laboratory. DPFPA can provide a speed-up equal to 4, with respect last generation PC, showing also a good scalability in terms of clock frequency, memory capability and number of computing units
