Is there any performance data on how the card does with a 5370A and / or a

will do some things with B firmware, that’s not the question I’m asking. I’m
looking for A to A or B to B timing data.
Yes. I made some measurements with the previous microcontroller-based board (48 MHz
sam7x) versus the stock CPU card. I have not yet had a chance to repeat that exercise
with the current board. Look at the 23-Jul-2011 entry on
<www.jks.com/5370/5370.html> Very much dependent on what the measurement is,
but a range of 5-72% faster.
Early in the beta process there where an issue which caused incorrect
readings and thus higher noise. It was resolved as I recall and noise
level fell back to expected.
Cheers,
Magnus
