Willsy Posted November 13, 2014 Share Posted November 13, 2014 You've all no doubt heard about the Philae lander making a world-first by actually landing on a comet out in deep space. What you probably didn't know, is that both the orbiter, and the lander itself are running on Forth! They both have Harris RTX2010 processors (native Forth CPUs) as their main CPUs. Go Forth! 2 Quote Link to comment Share on other sites More sharing options...

JonnyBritish Posted November 13, 2014 Share Posted November 13, 2014 Here is the article talking about it http://www.cpushack.com/2014/11/12/here-comes-philae-powered-by-an-rtx2010/ Willsy, you are going to space harden your upcoming quad Forth processor just in case NASA calls you :-) 1 Quote Link to comment Share on other sites More sharing options...
+Gemintronic Posted November 13, 2014 Share Posted November 13, 2014 The backup has been well tested as on each power cycle of Philae the backup computer has started, then handed control over to the primary. This technically is an anomaly, as the CDMS was not programmed to do so, but due to some unknown cause it is working in such a state. Apparently this is Cyberdyne technology. Expect terminators when this thing returns! Quote Link to comment Share on other sites More sharing options...
+OLD CS1 Posted November 13, 2014 Share Posted November 13, 2014 Apparently this is Cyberdyne technology. Expect terminators when this thing returns! This is due to its base RPN-like nature... they just put the backup in the wrong place in the stack But, what happens if the backup fails? Does control then not hand over to the primary? I sure hope that does not happen. Quote Link to comment Share on other sites More sharing options...
Wildstar Posted November 13, 2014 Share Posted November 13, 2014 (edited) Cool, next generation would probably be space hardened version of the GreenArray GA144s which would be quite fast. Okay, this may require some significant engineering for making the chip suitable for radiation resistance.

Wildstar Posted November 13, 2014 Share Posted November 13, 2014 (edited) Just tells how real and relevant Forth is in solving mission goals and also the flexibility of the language which is in some sense its 'operating system'. It's quite flexible for sure. Edited November 13, 2014 by Wildstar Quote Link to comment Share on other sites More sharing options...

Wildstar Posted November 13, 2014 Share Posted November 13, 2014 So-Jupiter Ace lands on comet. Kinda. Just that the processor is a "Forth" cpu in that the ML is Forth in a sense. It's a single cpu predecessor of the F18A computer architecture used in GreenArray GA144 chips which is an 18bit Forth computer. (NOTE: Not to be confused with the F18A VDP upgrade).

+Ksarul Posted November 14, 2014 Share Posted November 14, 2014 I'm not sure if Cyberdyne is using Forth processors in their hardware yet. . .but they are definitely into robotics. http://www.cyberdyne.jp/english/ 1 Quote Link to comment Share on other sites More sharing options...

The RTX2010 is a descendant of Chuck Moore's Novix processor. Harris moved the stacks inside the chip and added floating-point support. I'm sure that Chuck would have taken some Novix ideas with him when he sat down to do the GA144 and the F18, though. I'm sure you're right. I'll ask him next time I speak with him. Chuck has quite a history with Forth CPUs, as I'm sure you know. There's a really nice synopsis here: http://www.cpushack.com/2013/02/21/charles-moore-forth-stack-processors/#more-875 Edited November 14, 2014 by Willsy Quote Link to comment Share on other sites More sharing options...
Wildstar Posted November 14, 2014 Share Posted November 14, 2014 You can also talk to Greg Bailey. Yes, it has some architectural structure simularity for sure. Dual Stack machine, etc. Quote Link to comment Share on other sites More sharing options...
