Abstract

An interpolation system that breaks a color transform interpolation function into several suboperations or subfunctions. The subfunctions produce intermediate function results. The intermediate results are stored in a cache as the function is evaluated. Cache management operations locate and assign a cache cell to the intermediate results. In a subsequent evaluation that requires the same intermediate results, the intermediate results are obtained from the cache. The cache look-up rapidly provides the intermediate results which are then used to complete the function evaluation.
