is touting its latest sensor as the industry's first three-axis high-resolution accelerometer with two embedded finite-state
These programmable blocks enable custom motion recognition
inside the sensor, reducing system complexity and power consumption in
motion-sensitive mobile phones and other smart consumer devices that let users
answer calls, turn the ringer on or off, or launch applications like a
pedometer, with a defined motion.
The embedded finite-state machines allow the user to
implement customized motion-detection-based applications with a high level of
flexibility, reducing the workload of the microprocessor by moving programming
functionality inside the sensor. These basic programs identify specific motions
or gestures, custom-defined in the instruction set that runs inside the sensor
firmware, and initiate associated actions or applications.
ST's LIS3DSH accelerometer provides accurate output across full-scale ranges of
Â±2g/Â±4g/Â±8g/Â±16g and boasts excellent stability over time and temperature.
Other features include power-down and sleep modes, an embedded FIFO (first-in
first-out) memory block, a temperature sensor, and a self-test function.

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
