Mapping Graphics Resources to Linear Arrays Using a Paging System

摘要

Memory resources that are stored in GPU-specific formats may be accessed as linear arrays by CPU applications. Shared virtual memory (SVM) support enables closer CPU/GPU interaction. This creates a need to efficiently access graphics data using SVM. CPU page mapping and memory management hardware may perform the address/data swizzling and tiled rendering translations required for GPU memory formats. As a result, CPU applications can access GPU resources as if they are stored in a linear array, while also using shared virtual memory.
