MixNet: An Energy-Scalable and Computationally Lightweight Deep Learning Accelerator - 2019

Mixnet: An Energy-Scalable And Computationally Lightweight Deep Learning Accelerator

Research Area:  Machine Learning

Abstract:

In this paper, we present a lightweight CNN model named MixNet which is easily scalable to different energy requirements in embedded platforms. The MixNet model uses two extreme bit-precisions that efficiently balances the model accuracy and energy consumption. The energy consumption in processing MixNet is managed by controlling the ratio between high-precision (16bit) and low-precision (1bit) paths. Since only two bit-precisions are required in designing a hardware accelerator, the control logic becomes simpler compared to other multi-precision accelerators. In addition, a reconfigurable multiplier is proposed to enable highly parallel MixNet computations for faster prediction and/or training. Overall, the energy efficiency in terms of run-time per unit power improves by 1.75 , 1.94 over the recently proposed reduced-precision CNN model.
