Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data re-arrangement is performed by a central processing unit, then data transfer efficiency is improved, but CPU processing cycles are consumed
Solution Approach 1:
The patent introduces a dedicated data re-arrangement processor as an intermediary component between the CPU and the graphics processing system. This specialized processor handles the pixel coordinate transformation and data re-arrangement tasks, freeing the CPU from these operations while maintaining efficient data transfer. The intermediary processor uses lookup tables to perform coordinate transformations without requiring CPU intervention.
2Ease of operation
If a large number of small primitives are created for data movement, then data transfer is simplified, but overhead inefficiencies increase
Solution Approach 1:
The patent segments the data re-arrangement process into distinct functional components: coordinate transformation, lookup table generation, and pixel data retrieval. Each component operates independently and efficiently, avoiding the overhead of creating numerous small primitives. The segmentation allows for optimized processing at each stage rather than handling many small data movement operations.
3Manufacturing precision
If the processor performs data re-arrangement on a pixel by pixel basis, then data format requirements are met, but system efficiency deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-calculating and storing coordinate transformation values in lookup tables before the actual pixel processing begins. The lookup tables contain pre-computed offset values that enable rapid pixel retrieval without real-time calculation overhead. This preliminary preparation maintains precise data formatting while dramatically improving processing efficiency.

AI summary
A method and method and apparatus for data re-arrangement includes the steps of receiving output pixel coordinates (X, Y) and obtaining an input pixel offset value (ΔS, ΔT), wherein the output pixel coordinate represents a location for a two dimensional matrix. The input pixel offset value is obtained in reference to initial input pixel coordinates (S, T) which may be received with the output pixel coordinates or calculated based on the input and/or output pixel coordinates. The input pixel offset value may be any type of representation that provides for a delta value, for example, (ΔS, ΔT) may represent a shift representation for the offset within a matrix array. The method and apparatus for data re-arrangement further includes retrieving an input pixel based on the initial input pixel coordinates and the offset value.
