Completely superior chip that Cortex-M3.
Though i couldn't program much for it so far - difficult to get contract jobs for.
Can do fast multiplication 32 x 32 bits.
You can even implement RSA very fast on that chip.
Runs at 70Mhz or so?
Usually writing assembler for such CPU's is more efficient by the way than using a compiler. Compilers are not so efficient, to say polite, for embedded cpu's.
Writing assembler for such cpu's is pretty straightforward, whereas in HPC things are far more complicated because of vectorization.
-->> ah, but this is not really a HPC application. It's a cluster computer architecture demonstration platform. The Java based arduino environment is pretty simple and multiplatform. Yes, it uses a sort of weird C-like language, but there it is... it's easy to use.
