DEVICE, SYSTEM, AND METHOD FOR BUFFERING PROCESSOR INTERRUPTS

Abstract

Disclosed herein is system for buffering processor interrupts from active input devices, such as Bluetooth devices, so that they are aligned with a video refresh rate. The system may include a processor that operates in a first operating mode (e.g., a low power mode) and, in response to an interrupt request, switch to a second operating mode (e.g., a higher power mode). The first operating mode may be different from the second operating mode (e.g., each with a different level of power consumption). The system may also include a video subsystem, in communication with the processor, that provides video information at a refresh rate. The system may also include an input subsystem, such as a wireless communication system, in communication with the processor, that receives an activity trigger representing an activity of a input device, such as a human input device, and provides, based on the refresh rate, the activity trigger to the processor as the interrupt request.

IPC Classes  ?

• G06F 3/038 - Control and interface arrangements therefor, e.g. drivers or device-embedded control circuitry
• G06F 3/0338 - Pointing devices displaced or positioned by the user; Accessories therefor with detection of limited linear or angular displacement of an operating part of the device from a neutral position, e.g. isotonic or isometric joysticks
• G09G 5/00 - Control arrangements or circuits for visual indicators common to cathode-ray tube indicators and other visual indicators
• G06F 3/02 - Input arrangements using manually operated switches, e.g. using keyboards or dials
• G06F 3/0354 - Pointing devices displaced or positioned by the user; Accessories therefor with detection of 2D relative movements between the device, or an operating part thereof, and a plane or surface, e.g. 2D mice, trackballs, pens or pucks
• G06F 9/48 - Program initiating; Program switching, e.g. by interrupt
• G06F 1/3296 - Power saving characterised by the action undertaken by lowering the supply or operating voltage
