Due to the recent progress in deep learning and neural acceleration architectures, specialized deep neural network or convolutional neural network (CNNs) accelerators are expected to provide an energy-efficient solution for real-time vision/speech processing, recognition and a wide spectrum of approximate computing applications. In addition to their wide applicability scope, we also found that the...
Processing-in-Memory (PIM), has recently been revisited as one of the most promising solutions to deal with the issue of bandwidth and power wall between processor and memory. In this paper, we propose a light-weight PIM architecture, approxPIM, which leverages approximate computing techniques to enable InMemory Processing in a realistic 3D-stacked DRAM, Micron's Hybrid Memory Cube (HMC). Using the...
This paper surveys how to use Convolutional Neural Networks (CNN) to hypothesize object location and categorization from images or videos in mobile heterogeneous SoCs. Recently a variety of CNN-based object detection frameworks have demonstrated both increasing accuracy and speed. Though they are making fast progress in high quality image recognition, state-of-the-art CNN-based detection frameworks...
The emerging nanophotonic technology can avoid the limitation of I/O pin count, and provide abundant memory bandwidth. However, current DRAM organization has mainly been optimized for a higher storage capacity and package pin utilization. The resulted data fetching mechanism is quite inefficient in performance and energy saving, and cannot effectively utilize the abundant optical bandwidth in off-chip...
Hundreds or thousands of wireless sensor nodes with limited energy resource are randomly scattered in the observation fields to extract the data messages for users. Because their energy resource cannot be recharged, energy efficiency becomes one of the most important problems. LEACH is an energy efficient protocol by grouping nodes into clusters and using cluster heads (CH) to fuse data before transmitting...
This paper extends the conditions of the cluster-based routing protocols in terms of general algorithm complexity of data fusion, general compressing ratio of data fusion, and network area with long distance. Corresponding three general evaluation methods to evaluate the energy efficiency of the cluster-based routing protocols such as LEACH, PEGASIS, and BCDCP are provided. Moreover, three facts are...
