Multiplier and Multiplication Method Using Hybrid Encoding

摘要

PURPOSE: A multiplying machine using hybrid encoding and a multiplication calculating method thereof are provided to minimize power consumption while improving a processing speed of multiplication by using the hybrid encoding. CONSTITUTION: A mode signal generator(100) generates a first or a second mode signal according to a bit value of a predetermined area of a multiplier by receiving the multiplier. A hybrid encoder(200) encodes an area including the predetermined area into a first or a second cardinal number according to the mode signal by receiving the multiplier. A partial product generator(300) generates partial products by receiving the output of the hybrid encoder and a multiplicand. An adder(400) adds the partial products together.
