Abstract
A circuit and corresponding method perform timestamp filtering. The circuit includes recursive filter logic that implements a recursive least-squares (RLS) filter. The circuit (i) generates a filtered timestamp from a received timestamp by filtering the received timestamp via the recursive filter logic. The recursive filter logic applies the RLS filter to a portion of the received timestamp. A number of bits of the portion is less relative to a total number of bits of the received timestamp. 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.
