DEVICE FOR CONTROLLING STATE MACHINE AND METHOD OF OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240320085 titled 'DEVICE FOR CONTROLLING STATE MACHINE AND METHOD OF OPERATING THE SAME
The abstract of the patent application describes a device with a port connected to a link that supports communication with another device. The device includes a controller that manages the link based on a link training and status state machine (LTSSM). The port can receive two training sequences through the link in a recovery state, with each sequence consisting of a first symbol containing a lane number or special symbol, and a second symbol with a loopback bit. The controller can transition from the recovery state to a loopback state in the LTSSM based on specific conditions in the received sequences.
- The device has a port connected to a link with one or more lanes for communication.
- A controller manages the link using a link training and status state machine (LTSSM).
- The port can receive two training sequences in a recovery state.
- Each training sequence includes a first symbol with a lane number or special symbol, and a second symbol with a loopback bit.
- The controller transitions from the recovery state to a loopback state based on the received symbols.
Potential Applications: - This technology can be used in high-speed communication systems. - It can be implemented in networking devices for efficient data transfer. - The device can be utilized in data centers for improved connectivity.
Problems Solved: - Ensures proper communication between devices. - Facilitates quick recovery in case of link failures. - Enhances the reliability of data transmission.
Benefits: - Improved link management for better communication. - Enhanced data transfer speeds. - Increased reliability in high-speed networks.
Commercial Applications: Title: Advanced Link Management Device for High-Speed Communication Systems This technology can be applied in networking equipment, data centers, and telecommunications infrastructure. It can improve data transfer speeds, reliability, and overall performance in high-speed communication systems.
Questions about the technology: 1. How does the device handle link failures and ensure quick recovery? - The device transitions to a loopback state based on specific symbols in the received sequences, allowing for efficient recovery in case of link failures.
2. What are the potential applications of this technology beyond communication systems? - This technology can also be utilized in industrial automation, automotive systems, and other fields requiring high-speed data transfer and reliable communication.
Original Abstract Submitted
a device includes a port connected to a link including one or more lanes to support communication between the device and another device; and a controller that controls the link based on a link training and status state machine (ltssm). the port may receive two received sequences, each defined as a training sequence, through the link in a recovery state included in the ltssm. the training sequence may include a first symbol, including a lane number or a special symbol, and a second symbol including a loopback bit. the controller may transition from the recovery state to a loopback state included in the ltssm, based on the first symbol including the lane number and the loopback bit being set to an active logic state, for both of the two received sequences.
