Patent Images
1. In a data processing system having a cache, a method for generating an uncached image comprising:
- locating a first component that is related to the uncached image, the first component including a component tag and a component payload, the component payload including image information, and the first component being present in either the cache or a storage system;
locating a second component that is related to the uncached image in either of the cache, the storage system, or another storage system, the second component including a second component tag and a second component payload, the second component payload at least including additional image information; and

Abstract
Methods and apparatus for constructing objects within a cache system thereby allowing the cache system to respond to requested objects that are not initially available within the cache system. One embodiment of the invention caches image files, where the images are divided into components and stored in a format that allows identification and access to the components. The cache system determines that an object, such as an image file, is missing from the cache memory, locates sufficient components from the cache memory and/or external storage, and constructs the object from the located components.
