Is anybody here familiar with GreenArrays?

[BrianMiller]

Just wondering if anybody here is following Chuck Moore and his microprocessor work. I ran into XMOS from the parallax propeller forums (Hi Leon!). Chuck's designs are simple and the instruction set can be learned in one evening though I suspect it takes near a life time to master using it.

I got some of the Intellasys S40 chips before Chuck and TPL parted company, they were expensive. I'm not sure if I'll do anything with them, though.

I'd not heard of GreenArrays, they look interesting:

I hope that Chuck has more success with them than he did with Intellasys.

I've checked out SeaForth, I didn't know about green arrays?
Chuck's certanly been busi, over the years, he's loves his work.
There's a group looking into developing Forth for XCore. I've not
learned Forth therefore I can't comment critically. There is, and
shall be a lot potential IP that one may target to augment XCore.

Can a 180nm process be competitive today regarding to MIPS/Power consumption?

[shawn]

180nm ? There's still a lot of applicable asic's. If said product comercializes
then 65nm is not a big deal. The lower you go the more resourse. There are
several chips for small app. say at 180nm that would fill watt, speed issues.
Good question liltroll, Who knows, score the right mix create neoIP get rich?

Interesting looking chips.

Reading the product brief it looks like their instruction set is based on ColorForth

They also have ADC and DAC on board which I feel we are missing from the XS1 chips.

It doesn't look like there is any silicon yet, but their web site states the GA144 chip has been fabricated as a pre-production shuttle run so they could be close to releasing a chip. The chips shown on the website are marked "internal use only".

I always thought the SeaForth chip would make a nice outboard ALU for the XCore.
That is not going to be my approach though, at least not right now...
