Abstract
Occurrences of a particular event in an electronic device are counted by incrementing an event counter each time a variable number of the particular events have occurred, and automatically increasing that variable number as the total count increases. The variable number (prescale value) can increase geometrically according to a programmable counter base each time the count mantissa overflows. The event counter thereby provides hardware-implemented automatic prescaling while significantly reducing the number of interface bits required to support very large count ranges, and retaining high accuracy at very large event counts.
