eCos has support for SMP.
eCos uses threads rather than processes. Threads are more efficient
for real time systems.
Why do you want virtual memory in a deeply embedded system? It normal
to run everything from real RAM and/or FLASH. eCos doesn't have much
disk support at the moment anyway, so there is no place to swap memory
to...
If you need multiprocessor, multi-procesing and virtual memory, it
sounds like you want a bigger OS, eg linux, *BSD etc.
