Four sources transmitting status data across across ethernet at
25Hz. Status data is periodic.  I have one source transmitting
aperiodic commands across a separate interface. Upon receipt of
a command I have to acquire the data within 40ms. Receipt of
command data has a higher priority than status data from four
sources.  The status data from the four sources is sent to the
one source. Similarily the command data from the one source is
sent to the four  I'm using Curtiss Wright Champ products and
I'm trying to architect this. The approach surrounds the use of
a watchdog timer with five tasks. The timer could run at 4 * 25
Hertz. That said on each 10ms tick,I'll: 10ms - parse data from
source 1. ( semGive ( source1_sema ) ; ) 20ms - parse data from
source 2 ( semGive ( source2_sema ) ; ) 30ms - parse data from
source 3 ( semGive ( source3_sema ) ; ) 40ms - parse data from
source 4 ( semGive ( source4_sema ) ; )  Trouble is 4 * 25 is
not enough time to handle the four sources + receive command
data. I've got th
