Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Selecting multiple preferred items sequentially from a set of ranked items consumes significant power and incurs processing delays.
Innovation Solution
An apparatus and method using selection circuitry with at least one selection node circuit to select two most preferred items by choosing a most preferred item from one pair and a least preferred item from another pair, without considering the relative ranking between them, allowing for parallel processing and reduced power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple preferred items are selected sequentially from a set of ranked items, then the selection accuracy is maintained, but power consumption increases and processing delay occurs
Solution Approach 1:
The patent divides the selection process into parallel segments by processing multiple item pairs simultaneously through separate selection circuits. Instead of sequentially evaluating items one by one, the system segments the ranked item set into pairs and processes each pair in parallel, maintaining selection accuracy while reducing overall processing time and power consumption.
Solution Approach 2:
The patent dynamically restructures the selection process by transitioning from a fixed sequential evaluation order to a flexible parallel processing architecture. Selection circuits can be activated and deactivated dynamically based on the number of items to select, allowing the system to adapt its processing depth and power consumption levels while maintaining accurate selection results.
2Measurement precision
If multiple preferred items are selected sequentially from a set of ranked items, then the selection accuracy is maintained, but processing delay increases
Solution Approach 1:
The patent segments the selection task into independent parallel operations by dividing ranked items into pairs and processing each pair simultaneously through dedicated selection circuits. This segmentation eliminates sequential waiting time while preserving the ability to identify the most preferred items accurately, thereby reducing processing delay without sacrificing selection precision.
Solution Approach 2:
The patent performs preliminary organization of ranked items into pairs before the actual selection process begins. By pre-structuring the data into comparable pairs and preparing selection circuits in advance, the system eliminates setup delays during execution and enables immediate parallel processing, thus reducing overall processing time while maintaining accurate selection outcomes.
3Loss of information
If sequential selection of preferred items is performed, then complete ranking information is utilized, but power consumption and processing delay increase
Solution Approach 1:
The patent extracts only the essential ranking information needed for selection by comparing items in pairs and identifying the most preferred item from each pair. Instead of utilizing complete ranking information for all items in a sequential manner, the system extracts sufficient information through parallel pair-wise comparisons, reducing the computational burden and power consumption while still achieving accurate selection results.
