I just want to add that the OMAP processors have similar facilities. All of them have some sort of DSP and the OMAP5 comes with "two Cortex-M4 processors for low-power offload and real-time control". > meaning that the additional > core is supported by a Linux driver which allows code to be transferred to > the > core and then run.

AFAIR there were attempts (or success) to run uCLinux on the OMAP5 subcores. Since they lack MMU it is a little limited. But do these nice things solve any real world problem? If we can't get a nice and working and well accepted stack on the main processor - how would a SoC specific subcore help? It adds fragmentation is not available everywhere, difficult to debug etc. BR, Nikolaus _______________________________________________ Community mailing list [email protected] http://lists.goldelico.com/mailman/listinfo.cgi/community http://www.tinkerphones.org
