ecos doesn't support processes, only threads. But it does support symmetric

http://www.3glab.org/ for memory protection. eCos 2.0 for power management.

No it's free even for commercial use, but this mailing list is all the
support you get. Red Hat sell technical support, development kits
(including fully tested and qualified development tools and eCos sources)
for your nominated hardware, training (including on-site if required), and
we will do any custom development or porting you want, too. We have many
happy customers. If you are interested, mail ecos-info@redhat.com.
