The Forth success stories tend to be really, really ancient, and therefore almost irrelevant. Much like Chuck's arguments for the merits of stack languages / machines. Processor pipelines have to be at least deep enough to do a wide multiplication or you're basically looking at a toy.

I actually have designed my own FPGA soft core barrel processor, it's a special blend of register and stack machine. The blend occurs by placing stacks under the registers themselves. I believe this allows a low register count, 2 operand architecture to be more efficient than it otherwise would be, which minimizes opcode size, and sidesteps most the crazy you get when trying to shoehorn most processes into a single stack environment.

But has clear downsides as well, the main one being the stacks can become easily corrupted by any process using them - this is true of any stack machine but you strangely never hear it come up in conversations with Forth types. Stack processors can eliminate much traditional processor state, but the stacks themselves contain state, which is often overlooked.

Have you seen his Green Arrays? Not sure what the best use case is, but primitive it ain't.

Multi-core F18A technology, each of which is a simple 18 bit processor. IMO, anything less than 32 bits (with internal 33 x 33 = 65 bit multiply) falls into the primitive category abyss.

Moore is an incredible salesman, I'll give him that.

Moore is an awful salesman but a skilled technologist, you have it reversed. He only recently got buyers for his recent processors, and he doesn't handle sales in any of his business endeavors.

Also, the chips he made before GA were 32-bit. He deemed it unnecessary, and the GA chips run miles around them.

I meant that he's a genius at the whole stack machine / language shaman thing.

32 bits are unnecessary?!? I suppose a 18 bit machine would run a lot "faster" than a 32 bit machine given certain data sets and loads, but I wouldn't want to do any audio DSP with it.

[kick]

Actually, audio DSP might be a bit better on them, too. They have the best power/instruction ratio on the entire planet, and given each chip has 144 entire computers on it, audio DSP should be no problem for them.

"...and given each chip has 144 entire computers on it..."

Entire computers? What decade is it again?
