    pulse counter



      I am interested in building a pair of 100 MHz pulse counters with an external trigger. (pulses come at random time, the trigger would be based on an encoder signal sending out a square wave)


      several people reported counting at  nearly the processor clock speed using the GPIO pins of an atmega chip:

      40MHz-Frequency counter with ATmega8

      before embarking in this activity ...

      1) is anything like this possible with edison ?

      2) would two cpus  give simultaneous sampling (i.e. better than ~1 ns?)

      3) any advice or pointer would be greatly apreciated.
