Non-zero activation-map values are represented as 1- to 4-bit events, and the NPU only performs computation on events rather than the entire activation map.Дevelopers вЂњcan look at the weights, and see non-zero weights, and try to avoid doing multiplication by zero weights,вЂќ Mankar said. Brainchip has quantized MobileNet V1 for 10-object classification with prediction accuracy of 93.1 percent after quantization to 4 bits.ДЄ byproduct of converting to the event domain is significant power savings due to sparsity. BrainChipвЂ™s quantization tool helps designers decide how aggressively to quantize on a layer-by-layer basis. While native SNNs (those written from scratch for the event domain) can use one-bit precision, converted CNNs require 1-, 2- or 4-bit spikes. Replacing it with a layer that recognizes incoming spikes gives the otherwise ordinary CNN the ability to learn via spike-timing dependent plasticity at the edge, eliminating re-training in the cloud.

The convolution operation is achieved in the event domain for most layers, but the final layer is replaced. вЂњPeople who are familiar with the TensorFlow or Keras APIвЂ¦ can take the application they are running on, same network, same dataset, with our quantization-aware training, and run it on our hardware and measure the power themselves and see what the accuracy will be.вЂќД¬NNs are particularly good at extracting features from large data sets, Mankar explained, and conversion to the event domain preserves that benefit.

вЂњOur runtime software is taking the fear out of вЂWhat is an SNN?вЂ™ and вЂWhat is the event domain?вЂ™,вЂќ Mankar said. Data can be converted to spikes, and trained models can be converted to run on BrainChipвЂ™s NPU.

BrainChipвЂ™s development boards are available for x86 shuttle PC or Raspberry Pi. The approach also allows for on-chip learning at the edge, a quality of SNNs that would be extended to converted CNNs. This is done by converting CNNs to SNNs and running inference in the event domain. Referred to as the вЂњevent domain,вЂќ spikes typically result from changes in sensor data (for example, changes in pixel colors in an event-based camera).ДЄlong with SNNs, BrainChipвЂ™s NPUs can also process convolutional neural networks (CNNs) like those typically used in computer vision and keyword-spotting algorithms at lower power than other edge implementations. That is, the brain recognizes both sequences and the timing of spikes.

Like the brain, an SNN relies on вЂњspikesвЂќ that convey information spatially and temporally. The company has developed a neural processing unit (NPU) designed to process spiking neural networks (SNNs), a brain-inspired neural network that differs from mainstream deep-learning approaches. Akida silicon is also available.Д«rainChipвЂ™s neuromorphic technologies enables ultra-low power AI for analyzing data in edge systems where extremely low-power, real-time processing of sensor data is sought. BrainChip is offering the tools to developers working with its spiking neural network processor in hopes of licensing its IP. Both kits feature the companyвЂ™s Akida neuromorphic SoC: an x86 Shuttle PC development kit and an Arm-based Raspberry Pi kit.

BrainChip, the neuromorphic computing IP vendor, launched two development kits for its Akida neuromorphic processor during this weekвЂ™s Linley Fall Processor Conference.
