Matched Buffer Decompression Circuit for Stall-Free Data Loading
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display devices face inefficiencies in data transmission due to pipeline stalls and increased decompression overhead, which can lead to decreased data compression ratios and increased energy consumption, particularly when transferring compressed data over large physical distances.
Innovation Solution
The implementation of a decompression circuit with matched buffers and clock signals that synchronize data loading to remove asynchronous delays, allowing data to be loaded into data elements in a single internal clock cycle, thereby reducing pipeline stalls and decompression overhead.

Engineering Contradiction Analysis
1Length of moving object
If data is transferred over large physical distances in display devices, then data transmission capability is improved, but pipeline stalls and decompression overhead increase
Solution Approach 1:
The patent divides the data transmission path into multiple segments by introducing intermediate buffers at strategic locations along the physical distance. These buffers segment the long transmission path into manageable stages, allowing data to be processed and forwarded incrementally, thereby reducing pipeline stalls and maintaining transmission efficiency over large physical distances.
2Length of moving object
If compressed data is transferred over large physical distances, then data transmission capability is improved, but decompression overhead increases
Solution Approach 1:
The patent performs preliminary decompression operations at intermediate buffer locations before data reaches the final destination. By initiating decompression earlier in the transmission path, the system reduces the total decompression overhead required at the end point, as data is partially processed along the way, thereby reducing energy consumption for decompression.
3Productivity
If matched buffers and clock signals are used to synchronize data loading, then data transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent synchronizes data loading by adjusting clock signal parameters (frequency, phase) to match the buffer loading rates. By changing clock parameters dynamically to align with buffer operations, the system achieves efficient synchronized data transfer without requiring complex buffer matching logic, thereby reducing device complexity while maintaining high transmission efficiency.
