Objective

The main objective of this paper is to implement fast saturated binary counters based on sorting network to improve the efficiency of designs involving summation of multiple operands.

Abstract

In this project, a novel method of fast saturated binary counters such as (7, 3), (15, 4), (31,5) and exact & approximate (4:2) compressors based on the sorting network. The inputs of the counters are first divided asymmetrically into two parts and fed them as inputs to the sorting networks to generate the reordered sequences, which can be solely represented by one-hot code sequences. By using this method, we construct and further optimize the (7, 3) counter that can perform better in maximum than other designs in delay, area– delay product, and power–delay product, respectively. Similarly, the (15, 4) counter is constructed, and it achieves shorter delay, while it significantly consumes less power and area. Besides, we also construct approximate (4:2) compressors based on sorting network. To analyze the performance of the circuits designed, they are embedded in 8 x 8 using Full adder, half adder & (7,3) counter, and for 16 × 16 bit multiplier using Full adder, half adder & (7,3) counter, (15,4) counter.
