＜正＞ In this paper,a 64 x 64 bit modified full-array multiplier using a new compression technique is *** multiplier is based on a modular array architecture with the block of an encoder to implement the modified Booth’s algorithm [1],the block implementing the Wallace’s tree [2],and the block of a 128-bit Carry Look-Ahead（CLA） *** input of an encoder is 16-bit long and the block implementing the Wallace’s tree consists of both 4-2 compressors and 6-2 compressors proposed in this *** those compressors,the propagation delay time of the proposed multiplier is about 5% reduced,compared to the multiplier which has a parallel structured architecture [4].Also the multiplier has easier design methodology due to the regular characteristics of the modular array architecture.
