Towards 4-bit Hardware Accelerator for Very Deep Neural Networks
Abstract
Low precision is critical in designing hardware accelerators for neural networks. Achieving hardware-friendly sub-8 bit precision for deep networks like ResNet-101 is challenging. In this talk, we introduce a simple quantization method which offers effectively 4-bit precision to deep networks at a negligible accuracy loss (<1% top-1 accuracy loss) and, as a realization of the quantization method, a hardware accelerator called OLAccel (outlier-aware accelerator).
