AUTONOMOUS DETECTION OF STATUS OF LINK BETWEEN INITIATOR DEVICE AND TARGET DEVICE IN UFS SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17457507 titled 'AUTONOMOUS DETECTION OF STATUS OF LINK BETWEEN INITIATOR DEVICE AND TARGET DEVICE IN UFS SYSTEM
Simplified Explanation
The abstract describes a method and device for autonomously detecting the status of a link between an initiator device and a target device in a Universal Flash Storage (UFS) system.
- The method involves determining if an Acknowledgement and Flow Control (AFC) frame is received from the target device before a turn-around timer expires.
- If the AFC frame is received within the timer period, the method identifies the link between the initiator and target devices as active.
- If the AFC frame is not received within the timer period, the method restarts the turn-around timer with a second time period to detect the link status.
Potential applications of this technology:
- Universal Flash Storage (UFS) systems
- Communication and data transfer between initiator and target devices
Problems solved by this technology:
- Autonomous detection of the link status between initiator and target devices in a UFS system
- Ensuring efficient and reliable communication between devices
Benefits of this technology:
- Improved reliability in detecting the link status
- Autonomous operation without requiring manual intervention
- Efficient utilization of the turn-around timer for detecting link status
Original Abstract Submitted
A method and an initiator device for autonomous detection of status of a link between the initiator device and a target device in a Universal Flash Storage (UFS) system. The method includes determining whether an Acknowledgement and Flow Control (AFC) frame for a data frame is received before expiry of a turn-around timer. If the AFC frame is received from the target device before expiry of the turn-around timer, then the method detects the status of the link between the initiator device and the target device as active. If the AFC frame is not received from the target device before expiry of the turn-around timer then, the method detects the status of the link between the initiator device and the target device by restarting the turn-around timer with a second time period.
