Field-Programmable Gate Arrays (FPGAs) are gaining considerable momentum in mainstream high-performance systems in recent years due to their flexibility and low power consumption. Still, FPGAs remain largely unavailable to software programmers due to programming and debugging difficulties that are inherent to standard Hardware Description Languages. The performance that hardware-oblivious software...

This paper deals with the evaluation of FPGAs resurgence for hardware acceleration applied to computed tomography on the back-projection operator used in iterative reconstruction algorithms. We focus our attention on the tools developed by FPGAs manufacturers, in particular the Intel FPGA SDK for OpenCL, that promises a new level of hardware abstraction from the developer's perspective, allowing a...
Past research and implementation efforts have shown that FPGAs are efficient at processing many graph algorithms. However, they are notoriously hard to program, leading to impractically long development times even for simple applications. We propose a vertex-centric framework for graph processing on FPGAs, providing a base execution model and distributed architecture so that developers need only write...
For decades, the streaming architecture of FPGAs has delivered accelerated performance across many application domains, such as option pricing solvers in finance, computational fluid dynamics in oil and gas, and packet processing in network routers and firewalls. However, this performance has come at the significant expense of programmability, i.e., the performance-programmability gap. In particular,...
