A 32‑bit Approximate Parallel Prefix Adder was developed using Brent‑Kung prefix structure with TSB‑CSA for high‑speed, low‑power computation. Implemented in Verilog HDL, synthesized on Spartan‑3E FPGA, it achieved 59.079 ns delay, 0.036–0.041 W power, and efficient resource usage. - View it on GitHub
