This paper presents a Versatile Multimedia Functional Unit (VMFU) which can compute six arithmetic operations, i.e. addition, subtraction, multiplication, MAC, interpolation, and SAD with different configurations. The VMFU is constructed on the basis of a row-based modified Booth encoding multiplier which consumes the lowest power among others according to our transistor-level simulations. Besides, we apply the Spurious Power Suppression Technique (SPST) to the proposed VMFU to decrease the wasted dynamic power dissipation. From the transistor-level simulations, the proposed VMFU dissipates 0.0142 mW/MHz under a 0.18um/1.8V CMOS technology. Adopting the SPST can reduce 24% power consumption with only a 15% area overhead.
