SEMICONDUCTOR DEVICE AND LINK CONFIGURING METHOD - A simplified explanation of the abstract

This abstract first appeared for US patent application 18373072 titled 'SEMICONDUCTOR DEVICE AND LINK CONFIGURING METHOD

Simplified Explanation

The semiconductor device described in the patent application includes a PCIe controller with a link training and status state machine (LTSSM) that performs a link-up by configuring lanes on multiple ports. The controller stores a reference value as a first preset based on a successful link-up, and verifies a second preset set by the LTSSM against this reference value to determine its validity.

PCIe controller with LTSSM for link-up and preset verification:

   - The controller configures lanes on multiple ports for link-up.
   - A reference value is stored as a first preset after a successful link-up.
   - Verifies a second preset set by LTSSM against the reference value for validity.

Potential Applications

The technology described in this patent application could be applied in various industries such as telecommunications, data centers, networking equipment, and high-performance computing systems.

Problems Solved

1. Ensures accurate configuration of lanes on multiple ports for successful link-up. 2. Provides a method to verify the validity of presets set by the LTSSM.

Benefits

1. Improved reliability and performance of PCIe controllers. 2. Enhanced data transfer speeds and efficiency. 3. Simplified troubleshooting and maintenance of semiconductor devices.

Potential Commercial Applications

Optimizing PCIe controllers for high-speed data transfer in networking equipment and data centers.

Possible Prior Art

There may be prior art related to PCIe controller configurations and link training processes in semiconductor devices. Research into existing patents and publications in this field could reveal similar technologies or methods.

Original Abstract Submitted

Provided is a semiconductor device that includes a plurality of ports and a PCIe controller. The PCIe controller includes: a link training and status state machine (LTSSM) configured to perform a link-up by configuring a plurality of lanes on the plurality of ports, and a memory storing a first preset as a reference value, the first preset being configured based on a successful link-up performed by the LTSSM. The PCIe controller is configured to perform a verification of a second preset that is configured by the LTSSM based on the reference value, to determine whether the second preset is valid.
