Here is a nice paper showing how XMOS devices can replace FPGAs in
many applications:

Interesting paper. I've looked at the XMOS parts before and never
been impressed, but that may have been because of no special need or I
just didn't spend much time at it. I have a design idea I am batting
around that the XMOS might be suitable for. Your paper doesn't say
much about program storage; I gather that other than the 8 kB OTP it
is off chip. You might want to include some links in your paper to
the web site. That would make it easier to get additional info.

It's not my paper! I just thought it might be of interest.

For programs larger than 8k, off-chip flash has to be used for program
storage.

The XMOS web site is here:

Sorry, I figured you were an XMOS employee... jumped the gun on that
one.

I took a harder look at the XMOS parts and the power consumption is
pretty high. I guess the per/MHz figure is no so bad, but at 160 mA
typ, it is no improvement over the FPGA on the board, in fact, it is
worse.
