Lpc2000

Sorry, this is not an LPC-specific question, but 

Does anyone have any experience with AES encryption on LPC and order of
magnitude speed?

I have been looking around the net and am about to try compiling some
code to benchmark.

Other figures I have seen, for example at IDEAs website, suggest an
encryption rate of .16 Mbps (160 kbps or 20k Bytes/s) for a 20 MHz ARM7.
(I don't know what key size that is for though). I've also seen a figure
of 700 cycles/256 byte block, which is in the same range I think.

When I get my own answers, I'll share here but I'd welcome anyone's
thoughts on crypto speeds.
