Akida IP
BrainChip’s first-to-market neuromorphic processor IP, Akida™, mimics the human brain to analyze only essential sensor inputs at the point of acquisition—processing data with unparalleled efficiency, precision, and economy of energy. Keeping AI/ML local to the chip and independent of the cloud dramatically reduces latency while improving privacy and data security.
Infer and learn at the edge with Akida’s fully customizable event-based AI neural processor. Akida’s scalable architecture and small footprint boosts efficiency by orders of magnitude – supporting up to 1024 nodes that connect over a mesh network.
Every node consists of four Neural Processing Units (NPUs), each with scalable and configurable SRAM. Within each node, the NPUs can be configured as either convolutional or fully connected. The Akida neural processor is event based – leveraging data sparsity, activations, and weights to reduce the number of operations by at least 2X.
An IP Platform
The most performant edge AI
architecture, Akida IP is also easy to
implement and evaluate.
MetaTF software provides a model zoo, performance simulation, and CNN model conversion. The Akida1000 reference chip is fully functional and enables working system evaluation. Our development systems (PCIe boards, Shuttle PCs, and Rasberry Pi) complement Brainchip’s IP and reference SoC to enable the easy design of intelligent endpoints.
Akida is Uniquely Essential
BrainChip’s IP fabric can be placed either in a parallelized manner that would be ideal for ultimate performance, or space-optimized in order to reduce silicon utilization and further reduce power consumption.
Entire neural networks can be placed into the fabric, removing the need to swap weights in and out of DRAM resulting in a reduction of power consumption while increasing throughput.
Additionally, users can modify clock frequency to optimize performance and power consumption further.

Highly Configurable IP Platform
Flexible and scalable for multiple edge AI use cases.
BrainChip works with clients to achieve the most cost-effective solution by optimizing the node configuration to the desired level of performance and efficiency.
Scale down to 2 nodes for ultra low power or scale up to 256 nodes for complex use cases.
Multi-pass processing provides flexibility to process complex use cases with fewer nodes increasing power efficiency.
Quantization in MetaTF converts model weights and activations to lower bit format reducing memory requirement.
One-Shot On-Chip Learning
BrainChip IP and Akida perform on-chip learning by leveraging the trained model as a feature extractor and adding new classes to the final layer.
Demonstrated edge learning for:
- Object detection with MobileNet trained on the ImageNet dataset.
- Keyword spotting with DS-CNN trained on the Google Speech
Commands dataset. - Hand gesture classification with a small CNN trained on a custom DVS
events dataset.
