SEMICONDUCTOR DEVICE AND SYSTEM INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18056790 titled 'SEMICONDUCTOR DEVICE AND SYSTEM INCLUDING THE SAME
Simplified Explanation
The patent application describes a semiconductor device that includes multiple ports for data exchange and an interface controller with a link training and status state machine (LTSSM). The LTSSM executes a sequence of states to establish a link between the ports, and this sequence is stored as a reference sequence in a memory. The interface controller adjusts the physical layer (PHY) parameters during a calibration operation until the executed sequence matches the reference sequence.
- The semiconductor device has multiple ports that exchange data with each other.
- The interface controller includes a link training and status state machine (LTSSM).
- The LTSSM executes a sequence of states to establish a link between the ports.
- The executed sequence is stored as a reference sequence in a memory.
- The interface controller adjusts the PHY parameters during a calibration operation.
- The calibration operation continues until the executed sequence matches the reference sequence.
Potential applications of this technology:
- Semiconductor devices with multiple ports requiring efficient data exchange.
- Systems that rely on high-speed communication between different components.
- Networking equipment, such as switches or routers, that handle large amounts of data traffic.
Problems solved by this technology:
- Ensures reliable and efficient link establishment between ports.
- Enables calibration of PHY parameters to optimize data transfer performance.
- Simplifies the process of adjusting PHY parameters during link training.
Benefits of this technology:
- Improved data transfer performance and reliability.
- Simplified calibration process for PHY parameters.
- Enhanced overall efficiency of semiconductor devices and networking systems.
Original Abstract Submitted
A semiconductor device includes: a plurality of ports exchanging data with each other in an interface; and an interface controller including a link training and status state machine (LTSSM), configured to execute link-up, setting a plurality of lanes to the plurality of ports, and a memory configured to store a sequence, in which the LTSSM succeeding in the link-up executes states, as a reference sequence. The interface controller changes at least one of the PHY parameters when a calibration operation of adjusting the PHY parameters starts until a sequence of the states, executed by the LTSSM to complete the link-up, matches the reference sequence.
