Characteristics

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 interrupt latency of only four processor cycles, which lends it well to realtime applications.

History

In 1983, Chuck Moore implemented a processor for his programming language Forth as a gate array. As Forth can be considered a dual stack virtual machine, he made the processor, Novix N4000, as a dual-stack machine. In 1988, an improved processor was sold to Harris Semiconductor, who marketed it for space applications as the RTX2000.

Example spacecraft that use the RTX2010
gollark: That information has been classified by GTech™ Research Team 1298-η.
gollark: They decay pretty fast, but in normal conditions travel fast enough that time dilation offsets this.
gollark: Obviously the gay field has associated gay bosons, and [REDACTED].
gollark: SHUT UP.
gollark: The intense gaydiation (gay radiation) converted from the photons passing through the area would [REDACTED]. Also it would probably break atoms and such, since those rely on electromagnetism working as usual.
