Maxim’s camera cube enables AI applications such as facial identification and keyword recognition to be embedded in low-power, cost-sensitive applications such as wearables and IoT devices.

Enabling ultra-low-power internet of things (IoT) devices to implement hearing and vision, the MAXREFDES178# reference design features the MAX78000 low-power microcontroller with neural network accelerator for audio and video inferences. The system also contains the MAX32666 ultra-low power Bluetooth microcontroller and two MAX9867 audio CODECs. The entire system is delivered in an ultra-compact form factor to show how AI applications such as facial identification and keyword recognition can be embedded in low-power, cost-sensitive applications such as wearables and IoT devices.

AI applications require intensive computations, usually performed in the cloud or in expensive, power-hungry processors that can only fit in applications with big power budgets such as self-driving cars. But the camera cube design, according to Maxim, demonstrates how AI can live on a low-power budget, enabling applications that are time- and safety-critical to operate on even the smallest of batteries.

The MAX78000’s AI accelerator is claimed to slash the power of AI inferences up to 1,000x for vision and hearing applications, as compared to other embedded solutions. The AI inferences running on the MAXREFDES178# also show dramatic latency improvements, running more than 100x faster than on an embedded microcontroller, according to the company.

The compact form factor of the camera cube at 1.6in x 1.7in x 1.5in shows that AI can be implemented in wearables and other space-constrained IoT applications. Maxim says the MAX78000 solution itself is up to 50 percent smaller than the next-smallest GPU-based processor and does not require other components like memories or complex power supplies to implement cost-effective AI inferences.
