High speed low power fixed-point multiplier and method thereof

Abstract

Provided are a high speed and low power fixed-point multiplier and method thereof. The multiplier includes: a partial product calculation unit for dividing input data into a plurality of bit groups, each bit group having a predetermined number of bits, generating partial products by independently multiplying a fixed coefficient for each bit group, and summing partial products included in a corresponding bit group, to thereby generate a summed partial products; and an adding unit for adding the summed partial products of each bit group generated from the partial product calculation unit.
