Embedded smalltalk

I am wondering if Squeak or any other smalltalk can be used in embedded controllers.

Re: Embedded smalltalk

What kind of controllers ? Embedded lately spans from chip-cards to
iPacs :-)

It's interesting topic. There are large numbers of embedded cpu, like ARM.......
But, the GC of Smalltalk is not realtime, it's a big problem for realtime control.

Hi,

In fact Tektronix using smalltalk to control their oscilloscopes.
Here is the reference:
http://www.smalltalkconsulting.com/html/SmalltalkSolutions2001%234.html
"Simple things like CRC cards came out of Tektronix, A long time ago that company did the OS for Oscilloscopes using Smalltalk and 512k of ram. "

Regards.
Liu.

The GC of Squeak is not realtime, but people have made Smalltalks with
realtime memory management.

The original OTI Smalltalk, which morphed into IBM's VisualAge for
Smalltalk, was real-time. When OTI reengineered it for IBM, one of
the first things they did was write a faster, but non-realtime,
garbage collector.

See http://www.oovm.com/ for a commercial system that might see the
light of day. I played with it a bit and it was pretty nice, though
they changed the langauge to improve its performance on very small
machines.
