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

You would most likely need a high speed timer to do this. The microprocessor can read the results but I’m not sure if the built in timers would be fast enough to record the events. You would have to define the parameters regarding accuracy. What are your acceptable tolerances? Ba

Here's what I don't get. One of the most important uses of SRAM and parallel EEPROM and Flash is as microcontroller memory. If you'll look over the datasheets of MOST of your simple MCU's you'll find something kind of important. Almost all of them multiplex 8 bits of the address
