Bit Position Extraction Circuit for Low-Delay Sensor Data Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In sensors with multiple elements, data extraction can lead to excessive power consumption and reduced signal processing efficiency due to arbitrary data generation based on use conditions, environment, and situations, causing delays in processing information related to sensor elements.
Innovation Solution
A data extraction apparatus comprising a data receiving circuit, a complement generating circuit, and a bit position extracting circuit that sequentially extracts bit positions containing target values by performing bitwise operations, minimizing delays and optimizing data processing by converting and initializing bit positions, thereby reducing the complexity of processing input data.

Engineering Contradiction Analysis
1Reliability
If all sensor elements are explored to find target data, then the target data can be found regardless of position, but power consumption becomes excessive and signal processing efficiency degrades
Solution Approach 1:
The patent extracts only the relevant target data from sensor elements rather than processing all elements. The data processing circuit identifies and extracts target data based on specific criteria (such as event conditions in dynamic vision sensors), eliminating the need to explore all sensor elements and thereby reducing power consumption while maintaining reliable target detection.

3Adaptability or versatility
If data is processed in arbitrary order, then all data positions can be handled, but processing delays increase
Solution Approach 1:
The patent applies preliminary action by pre-defining specific data positions or patterns that are likely to contain target information based on the sensor application. Instead of arbitrarily processing all data positions, the system prepares and processes only the predetermined relevant positions, thereby reducing processing delay while maintaining the ability to handle various data positions through the configurable nature of the data processing circuit.
