BrainChip has introduced the Akida Pico, a new chip designed for ultra-low power AI inference, specifically targeting battery-powered devices. This innovation is part of the growing field of neuromorphic computing, which draws inspiration from the human brain's architecture and functioning. Steven Brightfield, the chief marketing officer of BrainChip, emphasizes that the design is tailored for power-constrained environments, where devices like smartwatches and mobile phones operate with limited energy resources. The Akida Pico is a miniaturized version of BrainChip's previous Akida design, consuming just 1 milliwatt of power or even less, depending on the application. This chip is aimed at the "extreme edge" market, which includes small user devices that face significant limitations in power and wireless communication capabilities. The Akida Pico joins other neuromorphic devices, such as Innatera’s T1 chip and SynSense’s Xylo, which have also been developed for edge applications. Neuromorphic computing mimics the brain's spiking nature, where computational units, referred to as neurons, communicate through electrical pulses called spikes. This method allows for energy-efficient processing, as power is consumed only when spikes occur. Unlike traditional deep learning models, which operate continuously, spiking neural networks can maintain an internal state, enabling them to process inputs based on both current and historical data. This capability is particularly advantageous for real-time signal processing, as highlighted by Mike Davies from Intel, who noted that their Loihi chip demonstrated significantly lower energy consumption compared to traditional GPUs in streaming applications. The Akida Pico integrates a neural processing engine, event processing units, and memory storage, allowing it to function independently in some applications or in conjunction with other processing units for more complex tasks. BrainChip has also optimized AI model architectures to minimize power usage, showcasing their efficiency with applications like keyword detection for voice assistants and audio de-noising for hearing aids or noise-canceling headphones. Despite the potential of neuromorphic computing, widespread commercial adoption has yet to be realized, partly due to the limitations of low-power AI applications. However, Brightfield remains optimistic about the future, suggesting that there are numerous use cases yet to be discovered, including speech recognition and noise reduction technologies. Overall, the Akida Pico represents a significant step forward in the development of energy-efficient AI solutions for small, battery-operated devices, with the potential to transform how these technologies are integrated into everyday applications.
