Apparatus and method for generating partial product for polynomial operation

摘要

An apparatus and a method for generating a partial product for a polynomial operation are provided. The apparatus includes first encoders, each of the first encoders configured to selectively generate and output one of mutually exclusive values based on two inputs. The apparatus further includes a second encoder configured to generate and output two candidate partial products based on an output from a first one of the first encoders that is provided at a reference bit position of the inputs, an output from a second one of the first encoders that is provided at an upper bit position of the inputs, and a multiplicand. The apparatus further includes a multiplexer configured to select one of the candidate partial products output from the second encoder.
