Before revision:  We introduce {\em Marvel}, which implements the above approach by leveraging two cost models to explore the two subspaces -- a classical distinct-block (DB) locality cost model for the off-chip subspace, and a state-of-the-art DNN accelerator behavioral cost model, MAESTRO, for the on-chip subspace.
After revision:  We implemented our approach in a tool called {\em Marvel}, which implements the above approach by leveraging two cost models to explore the two subspaces -- a classical distinct-block (DB) locality cost model for the off-chip subspace, and a state-of-the-art DNN accelerator behavioral cost model, MAESTRO, for the on-chip subspace.
