Abstract: Technologies for signaling compression inside a partially unrolled decision feedback equalizer (DFE) are described. The signaling compression associated with partially unrolled DFE results in multiplexers selecting a 1-bit output value from one of two 1-bit input values, which are decoding the actual multi-bit candidate levels and transforming the selected 1-bit output value to a multi-bit sliced value by adding to it a pointer value of a pulse-amplitude modulation (PAM) level. The signaling compression reduces the power and area of an N-tap DFE, where N is a positive integer.
