ISM330IS, 1st Sensor with Intelligent Sensor Processing Unit for Greater AI at the Edge
“Machine learning applications are increasingly common and many associate them with high memory requirements, cloud computing servers, or highly-parallel GPU architectures. And many programs do require expensive computational operations, making them incompatible with edge processing. However, companies also know that not all deep learning systems need this power. As a result, running inferences on mobile devices, such as smartphones, or on local industrial installations, is gaining traction. Image recognition, anomaly detection, and predictive maintenance all demand reliable AI performance in a tight power envelope. Similarly, cameras for wireless home security systems use AI to recognize faces or pets, and an ISPU could offer the intelligence for always-on displays on mobile systems.
The ISM330IS is a new answer to this challenge as it only requires 0.59 mA in high-performance mode. Comparatively, the ISM330DHCX needs up to 1.5 mA under similar conditions. The latter has a more powerful gyroscope, among other things, which does partly explain the difference. However, the numbers also show the optimizations that went into the new device and the efficiency of the processing core. Indeed, it is rare for low-power microcontrollers to have an FPU as they often demand a lot of energy. Yet, the ISM330IS still manages to keep its power consumption low enough to fit battery-powered systems…“
