Design and analysis of 3D-MAPS: A many-core 3D processor with stacked memory

We describe the design and analysis of 3D-MAPS, a 64-core 3D-stacked memory-on-processor running at 277 MHz with 63 GB/s memory bandwidth, sent for fabrication using Tezzaron's 3D stacking technology. We also describe the design flow used to implement it using industrial 2D tools and custom add-ons to handle 3D specifics.
