[chbot] multicore uP

[Mark Atherton]

Hi Volker,

"20 bucks (all American), same as the dev board, what's the problem? (Read the tools notes, you may need 2.)"


Yup, but there is NZ$125 minimum order for free shipping to NZ.using Digikey.

Failing that you can order in US$ and expect to pay US$45 shipping to NZ using Digikey.

... unless their shipping rules have changed.

============

In terms of the architecture, it follows in the path of the Transputer, and a parallel C looks quite interesting, if not even a tad cool.

============

The toolchain seems not to be too bothersome in terms of licencing, but as you say may take a while to get up the learning curve.

One application that they support is multi-channel audio over USB, along with royalty free Win32 drivers - which does interest me.

Digikey only has links to PDFs with more pages than I want to glance
over, no toolkit info.

Their home page says at the bottom "download toolkit", and it's gnu
binutils/gdb + eclipse based and multiplatform and one doesn't get the
run-around to find that info (beats Microchip). Don't expect "free" to
be open source though, they seem to have a proprietory compiler (doesn't
beat Microchip), but I'm not sure.

It's a completely different and let's say proprietory architecture. If
you have a specific purpose for it use it, but I'd expect the learning
investment to be high. Don't be too fooled by the MIPS numbers, that'll
be all 20 cores added up. Unless you write your program carefully to
make use of it you have a lot of unused silicon.

No, and I'd stick with ARM myself unless I had a very good reason not
to.

20 bucks (all American), same as the dev board, what's the problem?
