Abstract	Energy-efficiency has emerged as a major barrier to performance scalability for modern processors. We note that significant part of processor's energy requirement is contributed by processor-memory communication. To address the energy issue in processors, we propose a novel hardware accelerator framework that transforms high-density memory array into a configurable computing resource to accelerate variety of tasks - both compute- and data-intensive. It exploits the block-based architecture of nanoscale memory to create a spatially connected array of lightweight processors, each of which uses a memory block as its local memory. The proposed framework provides some unique advantages for hardware acceleration compared to conventional accelerators: 1) memory array provides large set of parallel resources with high bandwidth, which can be configured to perform computing in spatio/temporal manner leading to dramatic reduction in processor-memory traffic; 2) it brings the computing engine close to the data, thus drastically minimizing the von Neumann bottleneck; 3) finally, it exploits the advances in memory technologies and integration approaches e.g. 3D integration to achieve better technology scalability compared to alternative reconfigurable accelerator platforms. Simulation results for several data-intensive applications show that the proposed computing approach provides significant improvement in energy-efficiency compared to software while achieving significantly lower hardware overhead.
