Abstract
Official abstract text for this publication.
In an embodiment, a display pipe includes one or more translation units corresponding to images that the display pipe is reading for display. Each translation unit may be configured to prefetch translations ahead of the image data fetches, which may prevent translation misses in the display pipe (at least in most cases). The translation units may maintain translations in first-in, first-out (FIFO) fashion, and the display pipe fetch hardware may inform the translation unit when a given translation or translation is no longer needed. The translation unit may invalidate the identified translations and prefetch additional translation for virtual pages that are contiguous with the most recently prefetched virtual page.
First claim
Opening claim text (preview).
What is claimed is: 1. A display pipe comprising: a plurality of image processing pipelines, wherein each image processing pipeline of the plurality of image processing pipelines includes a fetch/memory management unit configured to fetch image data for that image processing pipeline, and wherein the fetch/memory management unit is configured to prefetch a plurality of translations to translate addresses of the image data, wherein the plurality of translations translate at least t…
