The need to support various recognition applications on energy‐constrained mobile computing devices has steadily grown. Exploiting common characteristics of recognition algorithms, a very energy‐efficient multiplier that can support a runtime trade‐off between computational accuracy and energy consumption is proposed. Compared to a precise multiplier, the proposed multiplier consumes 11.6×–3.2× less energy per multiplication while achieving 82–99% of the computational accuracy with negligible negative impact on recognition accuracy for three different recognition applications.
