A high-throughput CNN super resolution (SR) processor is proposed for memory efficient SR processing. It has three key features: 1) selective caching based layer fusion to minimize external memory access (EMA), 2) memory compaction scheme for smaller on-chip memory footprint, and 3) cyclic ring core architecture to increase the throughput with improved core utilization. As a result, the implemented processor achieves 60 frames-per-second throughput in generating full HD images.
