Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern telecommunication devices face challenges in efficiently managing large communication channels due to the need for high-speed processing of information frames, with existing framing technologies either being costly or inefficient in handling multiple protocols and error correction.
Innovation Solution
A method and device that optimize framing operations by fetching and reusing metadata for consecutively framed data chunks, reducing the number of instructions required and enabling simultaneous output of framed data chunks, while supporting HDLC compliant framing and error correction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional framers process one data chunk at a time with full metadata fetching for each operation, then framing accuracy and protocol compliance are maintained, but processing speed decreases and instruction overhead increases
Solution Approach 1:
The patent applies preliminary action by fetching metadata for multiple consecutive data chunks in advance, before the actual framing operations begin. The system pre-loads metadata into buffer descriptors, so that when framing operations need to process multiple chunks, the metadata is already available in memory rather than requiring repeated fetch operations for each chunk. This significantly reduces the time loss associated with sequential metadata access.
Solution Approach 2:
The patent uses copying by creating buffer descriptors that contain copies of metadata for multiple data chunks. Instead of accessing original metadata sources repeatedly, the system creates descriptor structures that replicate necessary metadata information, allowing rapid access during consecutive framing operations without repeated fetch cycles.
2Productivity
If framers duplicate processing components to increase throughput, then framing speed improves, but device complexity and cost increase
Solution Approach 1:
The patent implements continuity of useful action by enabling a single framer to process multiple data chunks in consecutive operations without idle periods between them. By pre-fetching metadata and organizing it in buffer descriptors, the framer can continuously perform framing operations on multiple chunks back-to-back, maximizing the utilization of the single framer component and achieving high throughput without duplicating hardware.
Solution Approach 2:
The patent applies segmentation by dividing the processing workload into discrete data chunks with associated buffer descriptors. This segmentation allows the system to organize multiple framing operations in a structured sequence, enabling efficient batch processing through a single framer while maintaining the ability to handle different protocols and error correction requirements for each chunk.
3Reliability
If framers perform additional operations such as CRC error correction for each data chunk, then data integrity and reliability improve, but processing time and instruction overhead increase
Solution Approach 1:
The patent merges multiple operations into a unified framing process. By combining data chunk framing, metadata retrieval, and CRC error correction operations into an integrated workflow using buffer descriptors, the system reduces the overall instruction overhead. The buffer descriptor structure allows the framer to perform framing and error correction in a coordinated manner rather than as separate sequential operations, improving efficiency while maintaining data integrity.
