Semiconductor Data Transmission Device Reducing Current Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Semiconductor systems face challenges in reducing current consumption during data transmission, as existing data transmission/reception devices consume power for each bit signal transmitted.
Innovation Solution
A data transmission/reception device is designed with a data bus and circuits that recognize standard data, generate flag signals, and load code data, reducing the number of bit signals transmitted by activating specific code bit signals only when the data value matches standard data, thereby minimizing current consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If all transmission bit signals are transmitted through the data bus, then complete data transmission is achieved, but current consumption increases
Solution Approach 1:
The patent extracts only the essential information needed for data transmission by comparing transmission data against pre-stored standard data. When a match is found, only the corresponding code bit signal is transmitted instead of all transmission bit signals. This extraction principle reduces the number of signals on the data bus while preserving the essential data information, directly addressing the contradiction between reducing current consumption and maintaining data transmission completeness.
Solution Approach 2:
The patent changes the parameter of data representation by converting standard data into compact code data with fewer bit signals. The code generating part transforms the data format from full transmission bit signals to a compressed representation using code bit signals that correspond to matched standard data. This parameter change allows the same information to be conveyed with fewer signals, reducing current consumption while maintaining data integrity.
2Use of energy by moving object
If code data with fewer bit signals is transmitted, then current consumption is reduced, but data transmission accuracy may be compromised
Solution Approach 1:
The patent applies preliminary action by pre-storing standard data in the code generating part before actual data transmission occurs. This pre-prepared standard data serves as a reference for converting transmission data into code data. By having the code generation rules and standard data ready in advance, the system can accurately convert and reconstruct data without loss of precision, even though fewer bit signals are transmitted. This preliminary preparation ensures data transmission accuracy is maintained while enabling current consumption reduction.
3Productivity
If standard data recognition is implemented, then data transmission efficiency is improved, but device complexity increases
Solution Approach 1:
The patent segments the data transmission process into distinct functional parts: a code generating part that stores standard data and generates code bit signals, and a transmission part that sends the coded data. This segmentation allows the standard data recognition function to be implemented in a modular fashion, improving data transmission efficiency while managing device complexity through functional division. The code generating part handles the complex recognition task separately from the transmission task.
