Even a slow processor should be fast enough.  Let's look at the 
math...

An object going 100 MPH will travel 1 inch in 0.568 ms.  Assuming a 
slow 1 MIPS processor, you'd get 568 instructions (counts) in that 
time.

In fact, that same processor could track something up to 56,800 miles 
per hour across that 1".
