- <p><em><span>Efficient summation of multiple operands in parallel is a crucial aspect of digital signal processing (DSP) systems. To enhance performance, high-compression-ratio counters and compressors play a vital role in accelerating the summation process. In this work, we propose a novel approach for designing fast saturated binary counters and exact/approximate (4:2) compressors utilizing sorting networks. The counter inputs are asymmetrically divided into two groups and processed through sorting networks, generating reordered sequences that can be efficiently represented using one-hot encoding. Three specialized Boolean equations are formulated to establish a direct relationship between the reordered sequence and the one-hot code, significantly simplifying the output logic of the counter. Using this methodology, we design and optimize a (7,3) counter that outperforms existing designs in terms of delay, area-delay product, and power-delay product. The proposed design is implemented using Verilog HDL, with simulation and synthesis performed on the Xilinx ISE tool, demonstrating its effectiveness in improving computational efficiency.</span></em></p>
