Hi,<br>
<br>
Having 1) sent out my original note (see below), 2) talked with many
of the relevant parties, and 3) having received no feedback to the
contrary, it is my understanding that all involved agree:<br>
<br>
a) To implement Dave and Ed's VME readout format in their modules.<br>
<br>
b) The modules will be ready by the time Hall D needs to read them
out (start this summer).<br>
<br>
If you do NOT agree with both of these please get back to me ASAP,
as we are proceeding with online and offline programming as if this
is the case.<br>
<br>
I note that this VME format may differ from that used by some
previously released modules (e.g. discriminators), but that having a
uniform format across all modules is more important.<br>
<br>
Thanks,<br>
<br>

Attached is Dave A's and Ed's proposal for a consistent data
format for all JLab front-end modules. At the last Online meeting
we were led to believe all JLab modules that get read out over the
VME backplane would implement this format (FADC25, FADC125, F1TDC,
TI, TS, etc). We are proceeding as if this is the case.
<br>
<br>
Further, we expect to begin reading out detectors this summer,
probably BCAL and FCAL first (check with Fernando for our crate
installation schedule). We would very much like this format to be
implemented by the time the crates are installed.
<br>
<br>
FPGA programmers: please let me know ASAP if you are NOT planning
to implement this format, or if you won't be able to implement it
by the time your modules get installed in Hall D and we begin
reading them out. We very much do not want to have to deal with
multiple formats for the same module (e.g. the June 2013 format,
the Mar 2015 format, whatever).
<br>
<br>
Finally, we are developing simulation, readout and analysis code
that expects this format, so we need to know ASAP if it will
change.
<br>
<br>
Thanks,
<br>
