Application-specific AI / DSP Accelerator

The SpiNNedge accelerator is designed for ultra-low-power processing and classification of time series from sensors in real time. It combines DSP functions for data preprocessing and feature extraction (frequency transforms, windowing, filtering, logarithm) with classification based on recurrent neural networks (RNN). The RNN module exploits sparsity for significantly reduced storage and processing effort. The accelerator performs individual processing layers autonomously. Complex layers can be flexibly assembled from base operations via a global control module.
