<br>
There are several commercially available MPSoCs:<br>
- MPPA from Kalray<br>
- TILE 64 from Tilera and it's Radiation Tolerant version Maestro<br>
- Xentium from Recore Systems<br>
but you need to investigate their OS support. Most of them should<br>
support some form of Linux SMP. Xentium supports RTEMS, but solely in<br>
the Leon core used to drive the system. These were used in several<br>
projects, so a simple google search should yield some interesting<br>
results.<br>
<br>
In terms of research, there are several EC funded projects that<br>
research time-predictability and MPSoCs/CMPs. I will leave links to a<br>
few of them as they might be of interest to your research:<br>
<br>
- T-CREST Time-Predictable Multi-Core Architecture for Embedded<br>
Systems: <a href="http://www.t-crest.org/" target="_blank">http://www.t-crest.org/</a><br>
- P-SOCRATES (Parallel Software Framework for Time-Critical Many-core<br>
Systems): <a href="http://www.p-socrates.eu/" target="_blank">http://www.p-socrates.eu/</a><br>
- PREDATOR: <a href="http://www.predator-project.eu/" target="_blank">http://www.predator-project.eu/</a><br>
- MERASA (Multi-Core Execution of Hard Real-Time Applications<br>
Supporting Analysability):<br>
<a href="http://ginkgo.informatik.uni-augsburg.de/merasa-web/" target="_blank">http://ginkgo.informatik.uni-augsburg.de/merasa-web/</a><br>
-parMERASA (Multi-Core Execution of Parallelised Hard Real-Time<br>
Applications Supporting Analysability):<br>
- CompSOC: <a href="http://compsoc.eu/" target="_blank">http://compsoc.eu/</a><br>
<br>
Although none of them focuses on the operating system itself, some<br>
include operating system ports and reason about the issues found in<br>
these kinds of systems.<br>
The T-CREST project includes a fully open source MPSoC<br>
(<a href="https://github.com/t-crest/" target="_blank">https://github.com/t-crest/</a>) that can be instantiated in a Xilinx<br>
platform. In addition, RTEMS is ported to the T-CREST MPSoC<br>
(<a href="https://github.com/t-crest/rtems" target="_blank">https://github.com/t-crest/rtems</a>) but solely in "pure" AMP<br>
configurations (fully decoupled and independent RTEMS instances<br>
running in each core). Nevertheless, I think adding support for RTEMS'<br>
multiprocessor extensions should be fairly easy.<br>
<br>
On the other hand, P-SOCRATES' objective is to develop a software<br>
stack aimed at bridging the gap between the application design and an<br>
hardware many-core platform. I guess this includes scheduling and<br>
operating system mappings, so it should be more aligned with your<br>
research.<br>
<br></blockquote><div>Great projects out there, I will have to see if I can use any of these projects, one or more of them maybe better than what my supervisor has suggested.
