Low power 3-D stacking multimedia platform with reconfigurable memory architecture.

ABSTRACTIn this paper, a low power and high performance three-dimensional (3-D) stacking multimedia platform called "3D-PAC" is proposed. This platform is a heterogeneous integration composed of a low power design logic layer (2D-PAC) and a reconfigurable memory tier via 3-D technology. After extensive 3-D architecture exploration with Electronic System Level (ESL) simulation, there is a 54% performance speedup compared with the former 2-D architecture for certain multimedia applications. This chip is fabricated in TSMC 90nm generic CMOS technology. The area of 2D-PAC is about 7880 x 7880 μm2 and the SRAM layer is about 3880 x 3880 μm2. Both layers are combined with 1,886 TSVs.
