How to get best repeatability on input response

[ATU]

if I wanted to trigger an output on the response of an input after a desired period of time in the order of microseconds, what would be the best approach to get the highest repeatability?  I was thinking either using an interrupt, wait a period of time and then fire the output or using the highspeed timer function tied to a table driven output. I need to be able to vary that time based on transmitted data or inputs.  Trying to get a comfortable feeling for what I could expect to base my calculations on for a job.

I'd use a high speed timer and a tab;e driven output. Should be good to 1us, every time.

Wow!

Sometimes I wonder if its my Do-More code with the bugs, or BobO's missed keystrokes in the inner workings of the machine.

BobO should probably spend less time on forums and more time coding...but it's become a bad habit. That I can quit any time. Seriously.

How else does a guy break free from writer's block?
I see you're using a FPGA as a CPU, how fast is that clocked at? just curious.

There are multiple processors and many different clocks, but the prevailing rate is 75Mhz.
