FORTH-based processors
Alan Tutt
with a computer design and now have the time to actually get around to
playing with the hardware aspect of it.
I had been looking very intently at the Harris RTX2000 and the Silicon
Composers SC32 chips, although neither fit my needs exactly. I can't
seem to find any information about newer chips that are optimized for a
FORTH architechure. I seem to remember that some companies offered
cell-libraries for custom chip designs, yet I am having trouble finding
out which one(s) have the core logics I am looking for.
Is there an online reference listing every processor made? IC Master
has a web-site, but I can't search for anything other that part numbers
there. Is my solution to purchase their book/CD?
I'm hoping that someone works closely with FORTH-based processors and
can direct me to find datasheets and such. Any help will be greatly
appreciated. Thanks.

The RTX2000 is not produced anymore.
Take a look at the F21 (http://www.dnai.com/~jfox/) and the
PSC100 (http://www.ptsc.com/)
And, of course, post again in comp.lang.forth.

Try:-
Patriot Scientific Inc. - PSC1000 ("ShBoom")
Ultra Technology Inc. - F21 and FPGA based processors.
The links are on either www.forth.org or www.forth.com
Asking in comp.lang.forth would also be a good place too.
I am re-organising my own pages at present and will advise when my own have
the links too.

I've been using the PSC1000 (ShBoom) from Patriot Scientific for a while
now. It's a great Forth engine, and available now, off-the-shelf for
$25 in small quantities, $10 in large quantities. www.ptsc.com for
details.
Cheers

The PSC1000 is, indeed, a great part. See our web site www.forth.com for
comparative benchmarks against other processors. AFAIK it's the only
commercially available Forth processor; the RTX family is now only available
as RAD-hard parts, ferociously expensive.
Cheers,
Elizabeth
Regnirps
are in open boot forth. Docs are free at apple.com. Old systems work through
the serial port, but new ones use keyboard and display. Its the best way to
debug a PCI or USB or FireWire driver or a video card, etc.

Ah, well, that's Forth in ROM; it's also present in all Sun workstations and
some other non-Intel platforms. I understood the question to regard real
Forth-based CPU architectures. Open Firmware (IEEE 1275), the system you're
referring to, can be implemented on any (preferably 32 bits & up) CPU.
Cheers,
Elizabeth
