MulticoreWare has announced the beta availability of key OpenCL tools and libraries for download from its website, writes Richard Wilson.

The company has worked with microprocessor firm AMD to provide support for OpenCL in multicore design incorporating graphics procesors (GPUs) and CPUs.

"We have worked closely with AMD to produce the fastest and most developer-efficient way to delivering optimised code for heterogeneous multicore environments, with full support for OpenCL standards and portability across platforms," said Curtis Davis, co-founder, v-p of engineering and chief operating officier at MulticoreWare.

Wind River has announced the immediate availability of Wind River Linux 4, Update Pack 2 - with graphics support to the forefront.

"As deeply embedded devices become more connected and complex, there is an increasing move towards richer graphics and more sophisticated user interfaces across a wide range of industries. We're rising to meet this need with the industry's first commercial embedded Linux to provide a pre-integrated hardware-through-middleware graphics stack for multiple hardware platforms," said Paul Anderson, vp of marketing and strategy for Linux products at Wind River.

Here's an Open Source-related story from our new Android blog, Eyes on Android - Android could be badly bitten by GPL licensing

A story on SlashGear suggests submerged issues about Android's licensing are becoming ever less subterranean... Google challenges Lodsys but Android faces legal firestorm over source sluggishness

Basically, it says that not all Android parties have been playing the Open Source game by the Open Source rules. The website makes the point that some Android OEMs may be keen to have 'Open Source' kudos without fully bothering about their side of the bargain...

Mentor Graphics has introduced a range of semiconductor design tools or integrated development environment (IDE) based on the open-source GNU toolchain, writes Richard Wilson.

Interestingly, the Sourcery CodeBench tool will provide support for the Xilinx range of ARM-based system-on-chip devices, called Zynq, which will be available later this year.

It also adds new support for Freescale's Kinetis embedded development platform.

Imperas - a virtualised software specialist, and a member of the ARM Connected Community - has released its first models of the Cortex-A family of ARM processor cores.

It says models of the ARM Cortex-A series of cores, along with models of the Cortex-M series of cores, are now available from Open Virtual Platforms (OVP - www.OVPworld.org/ARM). These include "example virtual platforms incorporating the cores and support for the cores in Imperas' advanced software development tools".

Low-Power Design is a new blog in the Electronics Weekly portfolio and it has an interesting open source-related post, concerning NXP and its recently-acquired low-power networking software.
