Re: [Open1451-devel] The question of IEEE1451.1 study

[Andrew S. <and...@gm...>]

Hello Chengyi,

sorry for a late reply.
First of all, I again advice you to post your questions to
ope...@li... mailing list because there are
other people familiar with 1451 and not just me, so there is a higher
chance to get your question answered.

Now to your questions..
At the time the paper was being prepared I used ACE 5.4.4. But I
didn't do anything special to shrink ACE. On of ideas in our papers
was that ACE was too large to port it to embeded 1451 system (in our
case even 1.8Mb was to large), so if we got it to be 7.8Mb we even
would have more arguments to prove that. Did you check any configure
time options before building ACE? Maybe you've included the whole
functionality. AFAIK, they have there some event framework which may
take space. Check some other options.

Concerning lib1451.so, as far as I remember we used gaithersburg tree
and not seattle. In gaithersburg project there is a demo with
Temperature NCAP emulation which we got running after fixing some
errors. So, pls, refer to it.

Unfortunately, I cannot provide you with neither libACE.so not
lib1451.a because AFAIK I deleted their sources from the server where
I compiled them and the process of building ACE is a bit time
consuming.

It would be nice to know where are you from and what is your
university and your project probably? Did you looked at 1451.0? Some
people say it can be enough in most cases.

Regards,
Andrew Stepanenko
