MEMORY ACCESS COMPRESSION USING CLEAR CODE FOR TILE PIXELS

Abstract:

One embodiment provides for a graphics processor comprising a translation lookaside buffer (TLB) to cache a first page table entry for a virtual to physical address mapping for use by the graphics processor, the first page table entry to indicate that a first virtual page is a valid page that is cleared to a clear color and graphics pipeline circuitry to bypass a memory access for the first virtual page based on the first page table entry in response to determination that the first virtual page is cleared to the clear color and determine a color associated with the first virtual page without performing a memory access to the first virtual page.
