QUEST: A Log-Quantized Deep Neural Network Engine with 3D Stacking SRAMs
Abstract
Deep neural network (DNN) is now fundamental machine learning technology in wide range applications. In use of edge computing, low-power inference accelerators of DNN are required for installing enough intelligence into embedded devices. In this presentation, we present a log-quantized neural network processor architecture and its LSI implementation. It employs hybrid datapathes of logarithmic region and linear region for eliminating the energy-consuming multiplier completely. The architecture supports variable bit-width of activation and weight values. Thus, computing performance and accuracy can be optimized to the application demands. In this talk, we introduce the design of our DNN processor and its evaluation results.
