incoming event, both events are still logically simultaneous. That means they
simultaneously arrive at the inputs of the multiplier, and the multiplier again
produces only one output event, with a value of –9.
Again, on the primary level you would have had two events at the output
of the Event Mult module. It is also not defined whether the event at the
output of the leftmost module would have been sent first to the inverter
or to the multiplier (although that is irrelevant for the given structure).
In general you can use the following rule to figure out whether two events are
simultaneous or not:
All events originating from (sent in response to) the same event are simultaneous.
All events originating from an arbitrary number of simultaneous
events (occurring at different outputs, but known to be simultaneous)
are also simultaneous.
The last example shows the benefit of having simultaneous events. In that case,
we eliminate the redundant processing of the second event by the multiplier,
which would have taken extra CPU time. In longer structures, in the absence
of simultaneous events, the number of events can grow uncontrollably unless
the structure designer pays particular attention to keeping the number of
duplicate events low.
In addition to saving CPU time, the concept of simultaneity leads to important
differences in one’s approach to structure construction, especially for the structures
implementing low-level DSP algorithms. You will become more familiar
with these differences as you start constructing your own structures.
