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.

gollark: [REDACTED]
gollark: I have something like five and nobody's noticed yet.
gollark: Surely a kitchen centrifuge is just an overclocked, bladeless blender.
gollark: But it was probably bad in some way, because I don't now.
gollark: I used to, I think?
