ABACUS parallel architecture was previously proposed as an alternate integer multiplication approach with column compression and parallel carry futures. This paper presents a VLSI implementation for ABACUS and benchmarks it against the conventional Wallace Tree Multiplier (WTM). Simulations are conducted with UMC180nm technology in Cadence environment. Although WTM implementation results in 26.6% fewer devices, ABACUS implementation has 8.6% less power dissipation with matched delay performance, due to 27.8% lower average activity.
