Five distinct departments are introduced: architectures (AA1–AA5), each offering unique trade-offs regarding power consumption, processing speed, and circuit area. These adders are incorporated into Wallace multipliers, which improve computational speed while lowering energy requirements and design complexity. The proposed designs are evaluated using 90 nm technology to determine their applicability in resource-constrained and error-tolerant domains, such as image processing, machine learning, and IoT applications. The findings demonstrate a versatile balance between accuracy and resource efficiency, making these designs well-suited for real-time systems with different performance demands.
