Xilinx launches new Xcell Software Journal Publication aimed at C/C++ and OpenCL programmers


Xilinx, Inc. announced immediate availability of the inaugural issue of Xcell Software Journal – a quarterly magazine for application and embedded software developers creating smarter, connected, and differentiated systems across fast-growing markets such as 5G Wireless, SDN/NFV, Video/Vision, ADAS, Industrial IoT, and Cloud Computing. The magazine targets developers programming in high-level languages like C/C++ and OpenCL to harness significant performance-per-watt and "any-to-any" connectivity advantages of Xilinx® All Programmable devices over traditional software programmable devices. Xcell Software Journal is available as a one-click PDF download or can be read online in iPad/iPod-compatible ISSUU electronic magazine format.

Open Source GPU capable of running OpenCL

In a white paper released during a semiconductor design conference last week in Silicon Valley, researchers from the University of Wisconsin-Madison outlined the architecture of the open source GPU dubbed MIAOW, or Many-core Integrated Accelerator of Wisconsin. The prototype was essentially designed to demonstrate an open source GPGPU compatible with OpenCL. The researchers said their goal was to emulate a full system, not to compete with commercial designs.

The PowerVR Imaging Framework for Android with OpenCL and EGL

The PowerVR Imaging Framework for Android comprises a set of extensions to the OpenCL and EGL Application Programming Interfaces (APIs) that enable efficient interoperability of software running on PowerVR GPUs with other components such as a CPU, ISP and VDE. These extensions enable the construction of shared memory allocations and software pipelines across multiple hardware components with no redundant memory copies (termed zero-copy). The framework is integrated at the library layer of the Android software stack, enabling efficient interoperability between APIs such as OpenCL, OpenGL ES and emerging APIs such as OpenVX.

A quick guide to writing OpenCL kernels for PowerVR Rogue GPUs

This Imagination Technologies article and a follow-up to be published next month introduce OpenCL programming for the PowerVR Rogue architecture. Starting with an overview of OpenCL programming fundamentals using a basic program, followed by an explanation of OpenCL execution on Rogue GPUs. This provides the background to understand the programming guidelines for the Rogue architecture which are illustrated by using a case study of an image filtering program.

Open Source Advanced Simulation Library written in OpenCL

Advanced Simulation Library (ASL) is a free and open source multiphysics simulation software package. Its computational engine is based, among others, on the Lattice Boltzmann Methods and is written in OpenCL which enable extraordinarily efficient deployment on a variety of massively parallel architectures, ranging from inexpensive FPGAs, DSPs and GPUs up to heterogeneous clusters and supercomputers. ASL is distributed under the free GNU Affero General Public License (AGPL) with an optional commercial license.
