Abstract: A circuit and corresponding method perform timestamp filtering. The circuit comprises input format-conversion logic that converts a received timestamp from an original format to an intermediate format. The circuit further comprises recursive filter logic coupled to the input format-conversion logic. The recursive filter logic generates a filtered timestamp in the intermediate format by filtering the received timestamp in the intermediate format.

The circuit outputs the filtered timestamp generated. Applying the RLS filter to the portion enables the circuit to be more efficient (e.g., smaller adders, fewer flipflops, etc.), thereby reducing area and power consumption of the circuit.
