Rolling texture context data structure for maintaining texture data in a multithreaded image processing pipeline
Abstract:
A multithreaded rendering software pipeline architecture utilizes a rolling texture context data structure to store multiple texture contexts that are associated with different textures that are being processed in the software pipeline. Each texture context stores state data for a particular texture, and facilitates the access to texture data by multiple, parallel stages in a software pipeline. In addition, texture contexts are capable of being “rolled”, or copied to enable different stages of a rendering pipeline that require different state data for a particular texture to separately access the texture data independently from one another, and without the necessity for stalling the pipeline to ensure synchronization of shared texture data among the stages of the pipeline.
