CACHE ARCHITECTURE FOR IMAGE WARP PROCESSING SYSTEMS AND METHODS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240095871 titled 'CACHE ARCHITECTURE FOR IMAGE WARP PROCESSING SYSTEMS AND METHODS

Simplified Explanation

The patent application describes a device with image processing circuitry that warps input image data to account for distortions associated with displaying the image on a display. The circuitry includes a two-stage cache architecture to efficiently generate the warped image data.

• The device includes a display for showing images based on warped image data.
• Image processing circuitry warps input image data to adjust for distortions related to displaying the image.
• The circuitry utilizes a two-stage cache architecture with a first cache and a second cache.
• The input image data is warped by generating mapping data for the warp and populating the first cache with the input image data.
• The second cache is populated with pixel values from the first cache based on a sliding window that moves according to the mapping data.
• Interpolation is used to generate pixel values for the warped image data.

Potential Applications

This technology could be applied in:

• Virtual reality headsets
• Augmented reality devices
• Image and video processing software

Problems Solved

Unanswered Questions

How does the two-stage cache architecture compare to other methods of image warping in terms of efficiency and accuracy?

The article does not provide a direct comparison with other methods of image warping, so it is unclear how the two-stage cache architecture stacks up against alternative approaches.

Are there any limitations or drawbacks to using this two-stage cache architecture for image processing?

The article does not mention any potential limitations or drawbacks of using the two-stage cache architecture, leaving room for further exploration into any potential downsides of this technology.

Original Abstract Submitted

a device may include a display for displaying an image frame based on warped image data and image processing circuitry to generate the warped image data by warping input image data to account for one or more distortions associated with displaying the image. the image processing circuitry may include a two-stage cache architecture having an first cache and an second cache and warp the input image data by generating mapping data indicative of a warp between the input image space and the output image space and fetching the input image data to populate the first cache. warping may also include populating the second cache with a grouping of pixel values from the first cache that are selected according to a sliding window that traverses the first cache based on the mapping data and interpolating between pixel values of the grouping to generate pixel values of the warped image data.
