Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by stationary object
If non-volatile memory is used to store configuration parameters, then power consumption is reduced and footprint is minimized, but frequent modification of startup parameters becomes difficult
Solution Approach 1:
The configuration data is segmented into multiple data segments with frame headers, allowing selective loading and modification of specific parameter groups without affecting the entire configuration set. This enables frequent modification of startup parameters while maintaining the energy efficiency of non-volatile memory for stable parameters.
Solution Approach 2:
A data loading method acts as an intermediary between non-volatile memory and the system registers, providing a buffer layer that facilitates frequent parameter modifications without directly accessing the non-volatile memory. This mediator enables adaptability while preserving the low power consumption characteristics of non-volatile storage.
2Adaptability or versatility
If all data segments are loaded into cache unit, then parameter modification becomes flexible, but loading invalid data wastes time and resources
Solution Approach 1:
Frame headers are loaded and verified before loading the actual data segments. This preliminary verification action identifies valid data segments in advance, preventing the loading of invalid data and saving time and resources while maintaining flexibility in parameter modification.
Solution Approach 2:
Only valid data segments identified through frame header verification are extracted and loaded into the cache unit. Invalid or corrupted segments are left out, ensuring efficient use of loading resources and time while maintaining the ability to modify parameters flexibly.
3Reliability
If verification of each data segment is performed, then data integrity is ensured, but processing time increases
Solution Approach 1:
Verification is performed preliminarily on frame headers before full data segment loading. This preliminary check ensures data integrity for critical configuration data while minimizing the impact on processing speed by avoiding redundant verification of already-validated segments.
Solution Approach 2:
Full verification is applied selectively to frame headers and only to data segments that require modification or are being loaded for the first time. Already-loaded valid segments are not re-verified unnecessarily, maintaining data integrity while optimizing processing throughput.
Data Source
AI summary
The present invention provides a data loading method. The method comprises: reading data from an initial address in a memory; obtaining a frame header identifier, loading a valid data segment comprising the frame header identifier; verifying the valid data segment; when it is determined that the verification is successful, sending at least part of information within the valid data segment to a cache unit; updating a register according to at least part of the information by the cache unit. Using a specific frame header identifier, loading data in the memory starts only from the specific frame header identifier, which skips the data before the frame header identifier and avoids loading invalid data in the cache unit, thus saving time, preventing lengthy program, and being more scientific and convenient.
