Abstract
A dynamically configurable portion of a cache shared between central processing and graphics units in a highly integrated multimedia processor is engaged as a secondary level in a hierarchical texture cache architecture. The graphics unit includes a small multi-ported Ltexture cache local to its 2D/3D pipeline that is backed by the relatively large, single ported portion of the shared cache. Leveraging the shared cache as a secondary level texture cache reduces system memory bandwidth and die size without significant sacrifice in performance.
