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.

F21 Microprocessor (in store), the foxchip.F21 Documentation. UltraTechnology's own second generation VLSI design by Chuck Moore using OKAD. Prototyped in .8u The prototypes have a CPU w/ 500mip/internal 240mip/sram 120mip/dram, 40 msps analog coprocessor, composite and RGB video coprocessor, serial/network router coprocessor, parallel port, rtc. Chips, software, prototypes in the UltraTechnology Store (this site). 500 MIPs in 1997 in .8u scaled to 1.2u and in .8u in 1998. In a modern fabrication process the parts would run four to ten times faster. Jeff Fox

Chuck Moore starts company named Async Array Devices in 2003 that is reborn in 2006 asIntellaSysthat makes Scalable Embedded Arrays designs in VLSI with Forth core. TheSEAforth24 and SEAforth40designs 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 GA4the GA32 and theGA144which 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.
