Hi!
Linux is no realtime system. The RTAI port for TS7200 is going on, but
is far from ready. Reading pulses is a trivial task for a PLD or uC, and
it seems a better option to count the pulses there and read it and
process int the SBC, but you app seems to me (from the vague description
above) more suited to be entirely done in a uC.
