Digital multipliers are a major source power dissipation in digital signal processors. Array architecture is a popular technique to implement these multipliers due to its regular compact structure. High power dissipation in these structures is mainly due to the switching of a large number of gates during multiplication. In addition, much power is also dissipated due to a large number of spurious transitions on internal nodes. Timing analysis of a full adder, which is a basic building block in array multipliers, has resulted in a different array connection pattern that reduces power dissipation due to the spurious transition activity. Furthermore, this connection pattern also improves the multiplier throughput. This array pattern is based on creating a compact tiled structure, wherein the shape of a tile represents the delay through that tile. That is, a compact structure created using these tiles is nothing but a structure with high throughput. Such a temporal tiling technique can also be applied to other digital circuits. Based on our simulation studies, a temporally tiled array multiplier achieves 50% and 35% improvements in delay and power dissipation compared to a conventional array multiplier. Improvement in delay can be traded for power using voltage reduction techniques.
