Manufactured by Intersil , the RTX2010 is a radiation-hardened stack - based microprocessor that has been used in numerous spacecraft .
Characteristics
It is a two stack processor that can stack 256 words each and supports direct execution of Forth . Subroutine calls and returns require only one processor cycle, and it also has a very low and consistent interrupt latency of only four processor cycles, which makes it well suited for real-time applications.
history
In 1983 Charles H. Moore implemented a processor for his Forth programming language as a gate array. Since Forth can be viewed as a dual-stack virtual machine, he built the Novix N4000 processor as a dual-stack machine. In 1988, an improved processor was sold to Harris Corporation , which marketed it as the RTX2000 for aerospace applications.
