Abstract
An apparatus comprises an edge detector, a memory and a pulse-input engine. The edge detector is configured to receive an input signal and a counter signal. The edge detector is further configured to send a set of time values based on the input signal and the counter signal. Each time value from the set of time values is uniquely associated with a detected edge transition from the input signal. The memory is coupled to the edge detector. The memory is configured to receive from the edge detector the set of time values. The memory is configured to store the set of time values. The pulse-input engine is coupled to the memory. The pulse-input engine is configured to measure a set of pulse-to-pulse delays based on the set of the time values stored in the memory.
