Abstract
Absolute value computation of binary numbers has important applications in digital signal processing and arithmetic operations, but conventional circuit designs usually face high latency and energy consumption problems. In order to improve computational efficiency, this paper proposes an optimization method based on logic gate circuits aimed at reducing the number of physical components and simplifying the circuit structure. By using a truth table for logic simplification, a more efficient 4-bit absolute value calculation circuit is designed in this study. Experimental results show that the optimised circuit performs significantly in reducing latency and power consumption and maintains the accuracy of the operation. The results of the study provide a better implementation of digital circuit design for application scenarios that require efficient computation.
