Arcon Sequencer TRAM
[There should be a picture here].
The Arcon digital waveform Sequencer TRAM is tasked with generating
the digital waveforms which control the CCD control electronics.
The definition of these waveforms is in the Wave Definition Language
(WDL)
source instructions, which are compiled into Nexus command macros.
The Nexus commands produce a binary waveform database which is downloaded
from the Nexus TRAM into the sequencer TRAM by a subsequent command.
Communications between the Nexus and Sequencer is routed by the
intervening
COMMNODE TRAM.
Nexus commands
The
NEXUS TRAM
responds to a number of
Sequencer commands
which generate the appropriate
seq.p protocol message and send it to the
Sequencer transputer.
There the
SeqMain program will act on the command as time permits
(the running of waveforms and handling hardware events takes priority).
A number of Nexus commands have been edited into an
initialization macro which controls
how the Sequencer starts up and what state it is in.
