Intermediate Buffer Routing for Fragmented Memory Decoding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information reproducing apparatuses face performance degradation due to excess overhead in data transfer and decoder control when resource data is not arranged in continuous memory areas, leading to inefficient decoding processes.
Innovation Solution
An information reproducing apparatus with a file cache management system that includes an intermediate buffer to ensure data continuity, using a change-over switch to route data through an intermediate buffer for decoding when data is not in continuous areas, and directly to the decoder when it is, optimizing data processing paths based on determination of data arrangement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If data are stored in divided memory areas, then memory management flexibility is improved, but data transfer overhead increases and decoding performance deteriorates
Solution Approach 1:
The patent introduces an intermediate buffer as a mediator between the divided memory areas and the decoder. This intermediate buffer consolidates data from multiple divided memory areas into a continuous data stream, allowing the decoder to process data efficiently without directly accessing fragmented memory regions. The intermediate buffer thus resolves the contradiction by enabling both flexible memory management and efficient decoding performance.
Solution Approach 2:
The patent segments the memory into multiple divided memory areas for flexible storage management, while simultaneously maintaining a separate intermediate buffer that provides continuous data flow to the decoder. This segmentation allows different parts of the system to operate optimally - the divided memory for flexibility and the continuous buffer for decoding performance.
2Productivity
If data are arranged in continuous memory areas, then decoding efficiency is improved, but memory management complexity increases
Solution Approach 1:
The intermediate buffer serves as an intermediary that handles the complexity of managing continuous data streams. It absorbs the memory management complexity by implementing its own buffering and data consolidation logic, while presenting a simple continuous data interface to the decoder. This resolves the contradiction by isolating the complexity in the intermediate buffer rather than in the overall memory management system.
3Stability of the object's composition
If an intermediate buffer is introduced, then data continuity for decoding is improved, but system complexity increases
Solution Approach 1:
The intermediate buffer is designed as a simple FIFO (first-in, first-out) structure that provides data continuity without complex processing. It simply collects data from divided memory areas and outputs it continuously to the decoder, maintaining data stability and continuity while adding minimal system complexity through its straightforward buffering mechanism.
