The original article was in 2010. It makes sense, but what was the impact two years down the line? I have yet to see a reasonably priced 4080 Freescale board, or a popular multi-core Linux port for it. It looks like X86 and possibly ARM will take this slot. As for virtualizing I/O? - why slow down something almost by a factor of 10 to 100 via emulation when the target is networking or packet inspection.

One of the major advantages of this approach in mobile handsetls will be in supporting rich media contents along with the strict RTOS functionality. The co-existance of an application OS and an RTOS has been explored successfully in the past (atleast experimentally). Personally I feel this concept will be eolving rapidly in the near future

@Kinnar: it is actually a good idea from Syed Shah! I believe he has made a strong case for the SoC but the article does not go further demonstrating or describing the use cases for such a technology. I wonder if ARM is planning something similar to that of FreeScale's that Shah is describing here. The article starts out on the premise of optimizing power consumption and then jumps to the SoC that integrates control and data planes. It doesn't fully explain how one can exploit its benefits at the physical layer. Reduction in power consumption can only be realized if the physical layer can effectively use the control plane's information through API's to make sure the hard assets are not over allocated or over used while some may remain unused. Perhaps some app notes are forthcoming? Dr. MP Divakar

Virtualization for embedded systems?? seems something new, why an embedded system will need it, as an embedded system requires an RTOS and RTOS plus virtualization it is something confusing.

Syed makes a good case for the bare-metal hypervisor approach to embedded virtualization. Have you tried it? What's your take?
