Memory Control Unit ECC Block Pre-encoding for Operation Speed
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data storage devices face limitations in operation speed due to sequential execution of data encoding and control signal generation, which can hinder performance in ubiquitous computing environments where rapid data access is essential.
Innovation Solution
Incorporating an error correction code (ECC) block that operates prior to the signal generation block, allowing for ECC encoding to be completed before control signals are generated, and utilizing a descriptor processing block to manage and instruct the ECC and signal generation processes, ensuring efficient data handling and control signal generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ECC encoding is performed sequentially before control signal generation, then data reliability is improved, but operation speed deteriorates
Solution Approach 1:
The patent applies preliminary action by performing ECC encoding in advance during the data input phase, so that encoding is completed before the control signal generation phase begins. This allows the encoded data to be ready when needed, improving operation speed while maintaining data reliability through proper error correction encoding.
Solution Approach 2:
The patent segments the data processing into distinct phases: data input phase, control signal generation phase, and data output phase. By separating ECC encoding into its own preliminary step within the input phase, the system avoids sequential bottlenecks and improves overall operation speed while ensuring reliability.
2Speed
If multiple processing blocks operate in parallel, then operation speed is improved, but device complexity increases
Solution Approach 1:
The patent divides the control unit into three independent processing blocks: data input block, control signal generation block, and data output block. Each block operates independently and can process data in parallel, improving operation speed while managing complexity through clear functional separation and standardized interfaces between blocks.
