3D stacked systems with on-chip DRAM provide high speed and wide bandwidth for accessing main memory, overcoming the limitations of slow off-chip buses. Power densities and temperatures on the chip, however, increase following the performance improvement. The complex interplay between performance, energy, and temperature on 3D systems with on-chip DRAM can only be addressed using a comprehensive evaluation framework. This paper first presents such a framework for 3D multicore systems capable of running architecture-level performance simulations along with energy and thermal evaluations, including a detailed analysis of the DRAM layers.
