One of the low cost devices that runs the EPICS software (both server

and some clients) is the Raspberry Pi.

Could you point me to some example of embedded device with low
resources (10K-100KB of memory, 8-bit processor, preferably bare metal
distribution), that supports the EPICS? I know that I am pushing the
limits, but the optimization (low power consumption) is an important
factor for us.

EPICS is not designed to run on such small systems, the smallest IOCs
would need to run RTEMS or VxWorks (or be ported to something similar)
and have 8-12MB of RAM, 16MB recommended. Anything smaller would need to
run custom code and communicate with a real IOC (which may be remote)
over a network, serial or field bus connection. This architecture can
protect the small system from being overloaded by communications
requests from other devices, and help keep your power consumption low.
