Ring Buffer Image Rotation for Variable Block Processing

The patent applies dynamics by making the block size variable rather than fixed. The block size is dynamically adjusted based on the rotation angle and the number of scan lines, allowing the system to adapt to different rotation scenarios. This resolves the contradiction by enabling larger effective processing blocks for small rotations while maintaining manageable block sizes for large rotations, thus reducing CPU processing time without restricting adaptability.

The patent changes the parameter of block size from a fixed value to a variable that depends on rotation angle and scan line count. By adjusting this parameter dynamically, the system can optimize processing efficiency for different rotation scenarios. This parameter change allows the output block size to scale appropriately, reducing CPU processing time while maintaining adaptability to various rotation angles.

Instead of increasing cache memory size statically, the patent uses dynamic block size adjustment based on rotation angle and scan line count. This allows the system to achieve high processing speeds for small rotations using moderate memory sizes, while handling large rotations through multiple passes. This dynamic approach improves productivity without proportionally increasing device complexity or memory requirements.

The patent segments the rotation processing into multiple passes when necessary, particularly for large rotation angles. Rather than requiring a single large cache memory to handle all cases, the system divides the processing into manageable segments that can be handled with smaller memory sizes. This segmentation maintains productivity while avoiding the need for large cache memory, thus reducing device complexity.

The patent introduces dynamic block sizing that adapts to rotation angle and scan line count, rather than using fixed blocks. This dynamic approach optimizes the number of memory accesses by adjusting block size to match the actual processing requirements. For small rotations, larger blocks reduce memory access overhead, while for large rotations, the system can use multiple passes with appropriately sized blocks, thus improving productivity without excessively increasing memory management complexity.

The patent changes the block size parameter based on rotation angle and scan line count, allowing the system to minimize the number of memory accesses. By adjusting this parameter dynamically, the system can process more data per memory access when appropriate, thereby reducing total data transfer volume while keeping memory management complexity manageable through systematic parameter adjustment.
