2023 EDGE AI TECHNOLOGY REPORT
Chapter X: The Future of Edge AI
In the coming years, the increasing demand for real-time, low-latency, and privacy-friendly AI applications will lead to a proliferation of Edge AI deployments. The latter will be continually more accurate and efficient, leveraging technological advances in communication networks (e.g., 5G and 6G networking), artificial intelligence (e.g., neuromorphic computing, data-efficient AI), and IoT devices. In this direction, the role of researchers and the open-source communities will be fundamental in driving the evolution of edge AI.
The development and deployment of efficient edge AI applications hinge on the evolution of different technologies destined to support edge devices and compute-efficient AI functions. Specifically, the following technological evolutions will shape the future of edge AI.
Event-based Processing & Learning:
BrainChip’s Neuromorphic AI Solution BrainChip is one of the pioneers of bringing neuromorphic computing to the edge. While traditional neuromorphic approaches have used analog designs to mimic the neuron and synapse, BrainChip has taken a novel approach on three counts.
• Firstly, not only do they support spiking neural nets, but they have applied event-based execution to traditional convolutional networks, thereby rendering neuromorphic computing mainstream today. This allows current CNN/RNN models to run much more efficiently and drives far more capable performance on extremely low-footprint, low-power devices at the sensor.
• Secondly, their design is a fully digital design that is portable and reliable.
• Thirdly, delivering on-device learning allows for personalization, customization, and other learning untethered from the cloud.
Brainchip’s Akida neural processor is offered as IP and is configurable from energy-harvesting applications at the sensor edge to high-performance yet power-efficient solutions at the network edge.
It is sensor-agnostic and has been demonstrated on a variety of sensors.
As a self-managed neural processor that executes most networks completely in hardware without CPU intervention, it addresses key congestion and system bandwidth challenges in embedded SoCs while delivering highly efficient performance. With support for INT8 down to INT1 and skip connections, it handles most complex networks today, along with spiking neural nets.
This led NASA to select BrainChip’s first silicon platform in 2021 to demonstrate in-space autonomy and cognition in one of the most extreme power- and thermally-constrained applications.
Similarly, Mercedes Benz demonstrated BrainChip in their EQXX concept vehicle that can go over 1000 km on a single charge.
In the latest generation, Brainchip has taken another big step of adding Temporal Event Based Neural Nets (TENNs) and complementary separable 3D convolutions that speed up some complex time-series data applications by 500x while radically reducing model size and footprint, but without compromising accuracy. This enables a new class of compact, cost-effective devices to support high-res video object detection, security/ surveillance, audio, health, and industrial applications. While neuromorphic computing is still discussed as a future paradigm, BrainChip is already bringing this paradigm to market.
