Abstract: A data input device includes a first delay line, a second delay line, a detection circuit, and a processing circuit. The detection circuit is configured to detect whether a first output data output to a system circuit deviates from a first detection range and to generate a first deviation signal in response to that the detection circuit detects the first output data deviates from the first detection range. The processing circuit normally takes a first delayed data delayed by the first delay line as the first output data. In response to that the processing circuit receives that the first deviation signal representing the first delayed data deviates from the first detection range, the processing circuit takes a second delayed data delayed by the second delay line as the first output data after the second adjustable delay magnitude of the second delay line is adjusted.

The key advantages of DNNFusion include: 1) a new high-level abstraction comprising mapping type of operators and their combinations and the Extended Computational Graph, and analyses on these abstractions, 2) a novel mathematical-property-based graph rewriting, and 3) an integrated fusion plan generation. DNNFusion is extensively evaluated on 15 diverse DNN models on multiple mobile devices, and evaluation results show that it outperforms four state-of-the-art DNN execution frameworks by up to 8.8× speedup, and for the first time allows many cutting-edge DNN models not supported by prior end-to-end frameworks to execute on mobile devices efficiently (even in real-time). In addition, DNNFusion improves both cache performance and device utilization, enabling execution on devices with more restricted resources. It also reduces performance tuning time during compilation.
