STMicroelectronics has announced the launch of its Intelligent Sensor Processing Unit (ISPU), which combines a digital signal processor (DSP) suited to run AI algorithms and MEMS sensor on the same silicon. It is designed to advance the sensor’s features to speed decision-making by reducing data transfers, enhancing privacy by keeping data local, while reducing size and power consumption.

In addition to reducing size over system-in-package devices and cutting power by up to 80%, merging sensor and AI puts electronic decision-making in the application Edge. Here, it helps to facilitate the Onlife Era where innovative products enabled by smart sensors are able to sense, process and take actions, enabling the fusion of technology and the physical world.

The Onlife Era acknowledges living with continuous assistance from connected technologies, enjoying natural, transparent interactions, and seamless transitions, with no discernible distinction between online and offline. With the ISPU, ST is enabling this era by helping to migrate intelligent processing into sensors that support the fabric of life: no longer at the Edge but in the Edge.

The product is easily programmable with commercial AI models and can ultimately operate with leading AI tools. Its ultralow-power DSP can be programmed in C, familiar to many engineers. It also allows quantised AI sensors to support full- to single-bit-precision neural networks. This enables efficiency in tasks such as activity recognition and anomaly detection by analysing inertial data.
