Reconfigurable Power-Aware Scalable Booth Multiplier

Abstract. An energy-efficient power-aware design is highly desirable for digital signal processing functions that encounter a wide diversity of operating scenarios in battery-powered intelligent wireless sensor network systems. To address this issue, we present a reconfigurable power-aware scalable Booth multiplier designed to provide low power consumption for DSP applications in highly changing environments. The proposed Booth multiplier makes use of a dynamic-range detection unit, a shared radix-4 Booth encoder, a shared configurable partial product generation unit, 8-bit/16-bit optimized Wallace-trees, a 4bit array-based adder-tree and a shared final carry-lookahead adder.
