Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High-speed data links often fail to detect and identify per-lane errors in data streams, necessitating the suspension of high-level data transfer to perform error detection.
Innovation Solution
Implementing circuitry in each lane of the receiver to perform error-detection operations, such as cyclic redundancy checks or binary parity checks, allowing for lane-specific error detection without suspending data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If error detection is performed on high-speed data links, then error detection capability is improved, but data transfer continuity deteriorates (requires suspension)
Solution Approach 1:
The patent divides the data link into multiple independent lanes, each equipped with its own error detection circuitry. This segmentation allows error detection to be performed independently on each lane without suspending the entire data transfer operation, thus maintaining productivity while improving reliability through per-lane error detection capability.
2Measurement precision
If per-lane error detection is implemented, then measurement precision is improved, but device complexity worsens
Solution Approach 1:
The receiver is segmented into multiple independent lanes, each with dedicated error detection circuitry. This segmentation enables precise per-lane error detection while managing complexity through modular design, where each lane operates independently with standardized detection logic that can be replicated across lanes.
Solution Approach 2:
Each lane is equipped with specialized error detection circuitry tailored to its specific function, allowing optimized error detection algorithms to be applied locally to each lane's data characteristics. This local quality approach improves measurement precision by adapting detection methods to lane-specific requirements while keeping each local circuit relatively simple.

AI summary
An exemplary method for performing lane-specific error detection in high-speed data links involves receiving, at a receiver, an ordered set of data from a transmitter communicatively coupled to the receiver via a data link. The exemplary method also involves identifying, in the ordered set of data, an error-detection reference. The exemplary method further involves performing, in connection with one data lane of the data link, an error-detection operation on the ordered set of data based at least in part on the error-detection reference. Various other devices, systems, and methods are also disclosed.
