Lax: Driver Interfaces for Approximate Sensor Device Access
2015
USENIX Workshop on Hot Topics in Operating Systems
Preserved Fulltext
We present Lax, a device driver abstraction for interacting with sensors that enables power savings in exchange for occasionally returning erroneous sensor data. ...
Because devices are accessed through interfaces provided by system software, exploiting the tolerable error for improvements in energy efficiency requires appropriate system software and hardware support ...
The Lax Device Interface System software interfaces for approximate device access should enable the specification of three types of tolerance to deviations from correct behavior: • Latency tolerances. ...
