Engineering Contradiction Analysis
1Reliability
If each functional circuit is equipped with multiple conversion circuits for various compression formats, then the data can be decompressed correctly, but the functional circuit becomes complicated and the area required increases
Solution Approach 1:
The patent introduces a transmission control circuit as an intermediary between the slave circuit (storage device) and the master circuit (functional circuit). This transmission control circuit contains the format conversion capability, acting as a mediator that converts data between different compression formats. As a result, the master circuit does not need to equip multiple conversion circuits itself, reducing its complexity while maintaining the ability to correctly process data in various formats.
2Reliability
If each functional circuit is equipped with multiple conversion circuits for various compression formats, then the data can be decompressed correctly, but the area required by the functional circuit is increased
Solution Approach 1:
The patent merges the format conversion functionality from the master circuit into the transmission control circuit. Instead of having conversion circuits distributed across multiple functional circuits, the conversion capability is consolidated in a single transmission control circuit that serves all master circuits. This merging reduces the total area required while maintaining comprehensive format conversion capability.
3Adaptability or versatility
If multiple functional circuits share the same storage device, then system resources are used effectively, but the amount of transmitted data significantly affects transmission performance
Solution Approach 1:
The patent applies parameter changes by dynamically selecting and applying appropriate compression formats based on the data characteristics and requirements. The transmission control circuit can adjust compression parameters and format selection to optimize transmission performance while maintaining resource sharing. This allows the system to balance between resource utilization efficiency and transmission performance by adapting compression parameters rather than using a fixed approach.
Data Source
AI summary
A data transmission system has a master circuit, a slave circuit, and a transmission control circuit. The slave circuit stores a plurality of data in a first format. The master circuit processes data in a second format to perform a corresponding function. The transmission control circuit is coupled to the master circuit and the slave circuit. The transmission control circuit accesses a first datum from the slave circuit according to a first access command of the master circuit, converts the first datum in the first format into a first application datum in the second format, and transmits the first application datum to the master circuit.
