The RTX2010, manufactured by Intersil, is a radiation hardened stack machine microprocessor which has been used in numerous spacecraft.
It is a two-stack machine, each stack 256 words deep, that supports direct execution of Forth. Subroutine calls and returns only take one processor cycle and it also has a very low and consistent [nterrupt latency of only four processor cycles, which lends it well to realtime applications.
