Have your programmers look into how that's done, as they'll need to learn how eventually....

If he plugs the encoder into the DSC, the pulses are read in hardware by the FPGA. 128,000 pulses per minute is only 2133 pulses/sec. The FPGA can easily handle that. Then his software just asks the FPGA for the count whenever it wants a reading.
