Abstract:

Long interconnects are becoming an increasingly important problem from
both power and performance perspectives. This motivates designers to adopt
on-chip network-based communication infrastructures and three-dimensional
(3D) designs where multiple device layers are stacked together. This talk
will present the challenges for L2 design and management in 3D chip
multiprocessors. Our first contribution is to propose a router
architecture and a topology design that makes use of a network
architecture embedded into the L2 cache memory. Our second contribution is
to demonstrate, through extensive experiments, that a 3D L2 memory
architecture generates much better results than the conventional
two-dimensional (2D) designs under different number of layers and vertical
(inter-wafer) connections.
