About

Using Deep Neural Networks (DNNs) in machine learning tasks is promising in delivering high-quality results but challenging to meet stringent latency requirements and energy constraints because of the memory-bound and the compute-bound execution pattern of DNNs. We propose a big-little dual-module inference to dynamically skip unnecessary memory access and computation to speedup DNN inference. Leveraging the error-resilient feature of nonlinear activation functions used in DNNs, we propose to use a lightweight little module that approximates the original DNN layer, which is referred to as the big module, to compute activations of the insensitive region that are more error-resilient. The expensive memory access and computation of the big module can be reduced as the results are only used in the sensitive region. For memory-bound models, our method can reduce the overall memory access by 40
