Recently I saw a low priced tablet "ARCHOS 80 G9" using a dual core OMAP4 processor from TI. I liked the HD video quality in that price. I was tempted but was not sure about the performance of OMAP4. Any experience to share?

Freescale says the key element of this "industry first" is "dual heterogeneous ARM Cortex A5 and M4 cores, respectively".

NXP has been shipping dual core Cortex M4+M0 for several months. Linux is of course a dog for realtime, so the second MCU for realtime tasks reflects this reality.

OMAP4, to my knowledge, uses the ARM Cortex-M3 as a system management core and does not give external API level access to the core. Freescale is giving full API access to the Cortex-M4 and it will be used as a real-time core or a off-load processor as the customer specific use case warrants.

How is Vybrid an "industry first" when OMAP4 has two Cortex-A9 and two Cortex-M3 processors, which can (I rather suspect) "simultaneously run both a high-level OS (Linux/Android) and a realtime OS (RTOS/MQX)"? (OMAP4 would be overkill for the uses targeted by Vybrid, but the "industry first" claim seems less qualified.)
