Low Power Mixed-Signal Binarized CNN Processor

Binarized Convolutional Neural Network (CNN) processor with mixed signal implementation has demonstrated ultra-low power operation capability in recent years. However low power advantage is valid at low signal to noise ratio (SNR) regimes, which limits the network size could be used thus sacrifice the computation capability. A mixed-signal binarized CNN processor, with group-based binarized CNN architecture is introduced. The SNR requirement of mixed signal processing is relaxed without sacrifices the network capability.
