The '''Novix NC4016''' was a 16-bit, [[stack machine]] [[microprocessor]] designed by [[Novix|Novix Inc]] in 1985 primarily for the [[Forth programming language]]. The NC4016 directly executes the primitives of the high-level Forth programming language. The NC4016 was capable of executing typical Forth programs as much as 20 times faster than the [[Motorola 68000]]. Novix also offered the NC4000 Small C Compiler which was compatible with the NC4016 microprocessor.

In 1988, the NC4016 design was licensed and improved by Harris Semiconductor which later rebranded the chip as the [[RTX2000]], a radiation hardened version suitable for spacecrafts use.

The NC4016 was later replaced by the [[Novix NC5016|NC5016]] and later by the [[Novix NC6016|NC6016]].

== History ==
In 1983 Charles H. Moore founded Novix, Inc, a company with the goal of designing a [[microprocessor]] that would execute FORTH programs optimally. The chip, which was originally named NC4000, was released as the NC4016 in June of 1985. The NC4016 was a completely stack machine. The opcodes manipulated the stack directly.

The microprocessor, which was fabricated using [[3μm|3 μm]] HCMOS process technology, has a 7.5MHz clock capable of 10MIPS.

== Implementation ==
Due to the limitations in the [[gate array]] technology of the time, the chip did not have any on-chip memory. Three separate modules were required: for the return stack, data stack, and program and data stack.
