High Speed And Low Power Data Compressors
The 3-2, 4-2 and 5-2 compressors are the basic components in many applications, in particular partial product summation in multipliers. In this paper, novel architectures and designs of high speed, low power 3-2, 4-2 and 5-2 compressors capable of operating at ultra-low voltages are presented. The power consumption, delay and area of these new compressor architectures are compared with existing and recently proposed compressor architectures and are shown to perform better. The proposed architecture lays emphasis on the use of multiplexers in arithmetic circuits that result in high speed and efficient design.
