The FORTH programming system is one of my favorites. The language is simple, compact, and extremely powerful, and almost dead. It has been kept alive over the years by a few fanatics including myself. Well, it looks like it is coming back in a big way. A lot of big names are now into the game.

PATRIOT SCIENTIFIC, which jointly owns a microprocessor related patent porfolio, said that Taiwanese firm Lite-On has bought a licence, becoming the third firm in a week to do so.

According to the firm, it's the first Taiwanese system company to buy a licence. Daewoo and a US manufacturer said they'd buy a licence earlier this week.

The firm's "Moore Microprocessor Patent Portfolio" that holds IP including seven US patents covering microprocessors, system on chip stuff, and microcontrollers.

This lot have also signed up for licences already. AMD, Intel, Hewlett Packard, Casio, Fujitsu, Sony, Nikon, Seiko Epson, Pentax, Olympus, Kenwood, Agilent, Lexmark, Schneider Electric, NEC Corporation, Funai Electric, Sandisk, Sharp Corporation, Nokia, Bull, Lego, DMP Electronics, Denso Wave, Philips, TEAC, Daewoo Electronics. And now Lite-On.
Now that looks like a rush. Why? Well, a dual stack architecture is pretty well fitted to C. Although C is no near as efficient as FORTH with such an architecture. EE Times Asia has more on the story.

Alliacense announced that Fujitsu Ltd has licensed its intellectual property protected by the Moore Microprocessor Patent (MMP) portfolio. Alliacense is the subsidiary created last year to administer the portfolio on behalf of owners Patriot Scientific Corp. and TPL Group Financial terms of the licensing arrangement were not disclosed.

Fujitsu becomes the third system manufacturer to publicly disclose licensing of the MMP portfolio, following Hewlett-Packard (HP) in January and Casio Computer Co. Ltd last week. In announcing the Casio deal last week, Patriot Scientific revealed that semiconductor makers like Intel Corp. and Advanced Micro Devices (AMD) are not being required to pay royalties on MMP licenses.
Note the earlier date. About a year and a half before the Dec 007 announcement. Also note that I have a friend who works for the TPL Group. I'll have to ask him what happened.

In any case a little more background from the March 006 article:
Patriot and TPL came together in June 2005 to settle a long-standing patent dispute so they could jointly pursue licensing revenue from third parties. The TPL Group has been granted full responsibility and authority for the commercialization and licensing of a unified portfolio of 10 patents.

The MMP portfolio is named after inventor Charles H. Moore, chief technology officer of TPL Group, who is known for inventing the Forth software programming language and for his work in the 1980s on stack-based microprocessors.
It looks like FORTH as a chip architecture is back big time. I wonder if the language will come back as well.

In any case I really like the Fujitsu 16 bit and the Fujitsu 32 bit versions of the architecture.

The Infineon TC1166 32 bit processor looks nice. Digikey sells them for about $39 ea. Quantity one. Since programming and hardware design is going to be the big cost for the initial units I'm going to do what Chuck Moore suggests. Get the biggest fastest processor you can afford to start. Then reduce the foot print if volumes warrant.
