摘要

我们提出了一个体积JPEG 2000编解码器的实现，作为gpu和多核cpu的软件加速的实际用例。我们提出了一种通用的方法来加速用C语言编写的现有代码。此外，我们考虑了处理数据的体积性质，并制定了相关的优化指南。由此产生的软件可以利用不同的加速器类型——gpu和多核cpu——并在各种硬件平台上以相对较小的工作量提供不错的加速。

Heterogeneous Acceleration of Volumetric JPEG 2000

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.
