Hmm - I spotted this the other day. Its interesting, but not cheap
(comparatively). However, "Spin" sounds interesting, being object
oriented, and offering a framework of objects. That sounds a lot like
the ooPIC. However, having a few PIC Micros or AVRs might acheive the
same, using C (which can deliver some abstraction), and would be
considerably cheaper.

After being a playstation 2 programmer, I am very aware that
multi-core programming can be a real headache - especially to debug.
If you are advanced enough to start getting parallel processing, would
one MC plus an FPGA be a better idea?

Now a chip that combined those, and offered lots of IO would be great
- you could then code your own PWM coders, I2C bus handlers etc as
systems on the FPGA, and the core of your code in a familiar MC

Now since some chip manufacturers can license a core you can buy for
an FPGA, then this might be acheivable.
