Implementation of a performance optimized database join operation on FPGA-GPU platforms using OpenCL

The growing trend toward heterogeneous platforms is crucial to meet time and power consumption constraints for high-performance computing applications. The OpenCL parallel programming language and framework enable programming CPU, GPU and recently FPGAs using the same source code. This eases software developers to implement applications on various devices supported by heterogeneous HPC platforms. This work presents two very different FPGA implementations of a database join operation, one using a direct O(n2) algorithm, and the other using a bitonic sort network to speed up the join operation. Comparison of performance and energy consumption for both FPGA and GPUs is provided which suggests a 40% performance/watt improvement by using an FPGA instead of a GPU

Image Processing Using FPGAs

This book presents a selection of papers representing current research on using field programmable gate arrays (FPGAs) for realising image processing algorithms. These papers are reprints of papers selected for a Special Issue of the Journal of Imaging on image processing using FPGAs. A diverse range of topics is covered, including parallel soft processors, memory management, image filters, segmentation, clustering, image analysis, and image compression. Applications include traffic sign recognition for autonomous driving, cell detection for histopathology, and video compression. Collectively, they represent the current state-of-the-art on image processing using FPGAs
