Deep Learning Inference: Performance validation on TX1

NVidia published a whitepaper （http://www.nvidia.com/content/tegra/embedded-systems/pdf/jetson_tx1_whitepaper.pdf） to take the investigation of GPU performance and energy efficiency for deep learning inference. To achieve high performance, Caffe and cuDNN 4 library are combined on TX1 to provides a series of optimizations for inference. cuDNN v4 applied in caffe to be optimized inference on small
