<p>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.</p> |
