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

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. | Due to the limitations in the [[gate array]] technology of the time, the chip did not have any on-chip memory.
