Forth Chips
This page contains references to many of the Forth chips
that I have heard about.
Online References:
Stack Computers is the definitive online
reference and should be required reading. Dr. Philip Koopman has graciously put
his book online. As the designer of several of the machines listed on this
page he provides a detailed overview of the subject and with his permission
several chapters of his book are cross referenced here.
Why Stack Machines? Dr. Philip Koopman.

Chuck Moore starts company named Async Array Devices in 2003 that is reborn in 2006 as
IntellaSys
that makes Scalable Embedded Arrays designs in VLSI with Forth core. The
SEAforth24 and SEAforth40
designs offer 24 or 40 650MHz Forth Core on small embedded chips. They also
produce designs with 48 200MHz Forth Core on FPGA.
Chuck Moore starts company named
Green Array Chips Inc. in 2009 that
produces a variety of multi-core Forth chips including the GA4
the GA32 and the
GA144
which can now be ordered. The GA144 has 144 Forth processors running at up to 666 Forth MIPS each.
They also offer and offers ArrayForth, a colorforth based development environment, and
development boards at their site. GA144 shown at SVFIG Forth Day 2010.
