5 Ways Embedded AI Processors are Revolutionizing Device Performance (Sponsored)

Artificial intelligence (AI) is moving from cloud-first architectures to edge-first designs, so more processing now runs on phones, cameras, and embedded controllers. Running inference on-device cuts latency and keeps sensitive data local. This momentum is reshaping product roadmaps, all due to different revolutions driven by edge AI. The Core Revolutions Driven by Edge AI Instead of routing every model and signal to the cloud, devices are processing more data locally to act faster and protect sensitive information. Because edge AI is changing where intelligence runs, IDC estimates global spending on edge computing reached about $261 billion in 2025. This rapid enterprise investment is due to several reasons. 1. Enabling Real-Time, On-Device Decisions Eliminating the cloud round-trip lets devices turn sensor input into action in milliseconds. This capability is essential for industrial automation and control loops because embedded AI processors run optimized models on-device, so decisions happen continuously. 2. Strengthening Privacy […]

ST’s Human Presence Detection (HPD) solution tracks head and posture with AI and VL53L8CP ToF sensor

VL53L8CP ToF sensor for AI presence detection

Back in 2022, we first saw STMicro launch the VL53L5CP ToF presence detection sensor for the PC market with features like user detection, gesture recognition, and intruder alert. Building upon that, the company has recently released its 5th‑generation Human Presence Detection (HPD) solution, built around the VL53L8CP 8×8 multizone Time‑of‑Flight sensor family with edge AI features offered as a turnkey solution for laptops, PCs, monitors, and accessories. We have seen and even tested earlier ToF sensors like the VL53L0X and VL53L1X, which used a single-photon avalanche diode (SPAD) for single-zone ranging. After that, we saw ST release the VL53L5, which was a major upgrade with up to 64-zone multi-zone support, enabling features like touch-to-focus and object tracking. Now, in the age of AI, ST has launched a 5th-gen turnkey HPD solution built around the VL53L8CP sensor. STMicro HPD solution specifications: Sensor – ST FlightSense VL53L8CP 5th generation multi-zone direct Time-of-Flight (dToF) […]

ST’s LSM6DSV320X – An AI-enabled IMU with two MEMS accelerometers for activity and shock detection

STMicroelectronics has introduced the LSM6DSV320X, a compact AI-enabled inertial measurement unit (IMU) that integrates a 3-axis digital gyroscope, a 3-axis low-g accelerometer (±16g), and a 3-axis high-g accelerometer (±320g) in a tiny 3 x 2.5mm package, ideal for space-constrained IoT devices such as wearables, smartphones, gaming controllers, smart tags, personal safety gear, and industrial monitoring systems. Most motion sensors are designed to track daily activities or detect sudden impacts, but the LSM6DSV320X is built to do both. One accelerometer tracks everyday motion up to ±16g, while the other handles high-impact events up to ±320g. One of the most interesting features is its adaptive self-configuration (ASC), which allows real-time adjustment of internal settings based on activity without the need for a host CPU, optimizing power use and responsiveness. It also includes a machine learning core (MLC) capable of running up to eight decision trees and a finite state machine (FSM) to […]
