Modern Deep Neural Network (DNN) accelerators are equipped with increasingly larger on-chip buffers to provide more opportunities alleviate the severe DRAM bandwidth pressure. However, most existing research on buffer utilization still primarily focuses single-layer dataflow scheduling optimization. As grow large enough accommodate weights in networks, impact of optimization communication diminishes significantly. Therefore, developing new paradigms that fuse multiple layers fully leverage...
