GRAU: Generic Reconfigurable Activation Unit Design for Neural Network Hardware Accelerators
Researchers have developed two novel architectures, ReSCom and SupraSNN, designed to improve the energy efficiency and performance of Spiking Neural Networks (SNNs). ReSCom utilizes stochastic computing for multiplication operations to reduce hardware complexity while maintaining stable inference, offering dynamic trade-offs between accuracy, latency, and energy consumption. SupraSNN, inspired by superscalar processors, physically decouples synaptic and neuronal computations to exploit synapse-level parallelism, achieving lower latency and better energy efficiency than previous FPGA-based SNN accelerators. Separately, a new design called GRAU offers a generic reconfigurable activation unit for neural network hardware accelerators, significantly reducing hardware cost and increasing flexibility for low-precision quantization.
