A New Design Technique for Column Compression Multipliers
نویسندگان
چکیده
In this paper, a new design technique for column-compression (CC) multipliers is presented. Constraints for column compression with full and half adders are analyzed and, under these constraints, considerable flexibility for implementation of the CC multiplier, including the allocation of adders, and choosing the length of the final fast adder, is exploited. Using the example of an 8 × 8 bit CC multiplier, we show that architectures obtained from this new design technique are more area efficient, and have shorter interconnections than the classical Dadda CC multiplier. We finally show that our new technique is also suitable for the design of two's complement multipliers.

A Design Technique for Faster Dadda Multiplier
AbstractIn this work faster column compression multiplication has been achieved by using a combination of two design techniques: partition of the partial products into two parts for independent parallel column compression and acceleration of the final addition using a hybrid adder proposed in this work. Based on the proposed techniques 8, 16, 32 and 64bit Dadda multipliers are developed and com...

متن کاملA Novel Data Compression Technique for 420 Ma Current Loop Transmitters
This paper presents a new data compression method for current loop transmitters. In this method, the 4-20 mA current domain is divided into some equal pieces that are used for distinct data domain with a constant relative resolution, resulting in widening the signal span. This technique eliminated the need for high resolution ADC’s or DAC’s in communication of 4-20mA current loop signals. Furth...
