Heterogeneous Acceleration of Volumetric JPEG 2000 Host Publication: PDP 2015 Authors: J. G Cornelis, J. Lemeire, T. Bruylants and P. Schelkens Publisher: IEEE Publication Year: 2015 Number of Pages: 8 ISBN: 9781479984923
Abstract: We present the implementation of a volumetric JPEG 2000 codec as a real-world use case of software acceleration with GPUs and multi-core CPUs. We present a generic methodology to accelerate existing code written in C with OpenCL. Furthermore, we account for the volumetric nature of the processed data and formulate associated optimization guidelines. The resulting software can exploit different accelerator types - GPUs and multi-core CPUs - and delivers a decent speedup on a variety of hardware platforms for a relatively small effort.
