So, how fast does your Signum device load into an LPC2000's flash?  Bet
it's not much faster than 14K/second and will never approach a "1M"
rate.  What's an "1M" rate?  Is that a TCK frequency or the programming
speed in bits per second or bytes per second?

The CrossConnect loads at over 180Kbytes/second onto an Evaluator-7T
into RAM, so that equates to a download speed of 1.4Mbit/second.  On
Xscale it's over 200K/second equating to 1.6Mbit/second.  Not too shabby
for a £99 device.  However, the Wiggler or one of its many clones isn't
at all bad for low-end development on small devices--about 1/5th the
speed for 1/5th the price (if you purchase a clone).
