In the 1980s, Moore turned his attention and Forth development techniques to
CPU design, developing several
stack machine microprocessors and gaining several
microprocessor-related patents along the way. His designs have all emphasized high performance at low power usage. He also explored alternate Forth architectures such as cmForth and machine Forth, which more closely matched his chips' machine languages. In 1983 Moore founded Novix, Inc., where he developed the NC4000 processor. This design was licensed to
Harris Semiconductor which marketed an enhanced version as the
RTX2000, a
radiation hardened stack processor which has been used in numerous
NASA missions. In 1985 at his consulting firm Computer Cowboys, he developed the Sh-Boom processor. Starting in 1990, he developed his own
VLSI CAD system, OKAD, to overcome limitations in existing CAD software. He used these tools to develop several
multi-core minimal instruction set computer (MISC) chips: the MuP21 in 1990 and the F21 in 1993. Moore was a founder of iTv Corp, one of the first companies to work on
internet appliances. In 1996 he designed another custom chip for this system, the i21. Moore developed the
colorForth dialect of Forth, a language derived from the scripting language for his custom
VLSI CAD system, OKAD. In 2001, he rewrote OKAD in colorForth and designed the c18 processor. In 2005, Moore co-founded and became Chief Technology Officer of IntellaSys, which develops and markets his chip designs, such as the seaForth-24
multi-core processor. In 2009, he co-founded and became CTO of GreenArrays, Inc which is marketing the
GA4 and
GA144 multi-computer chips. ==Publications==
