Patent ID: 7619631

Claim:
A graphics system for performing an anti-aliasing operation to generate filtered data for display, the graphics system comprising: a first graphics processing unit coupled to a first video memory, wherein said first video memory further includes a first frame buffer containing a first subset of said filtered data; a second graphics processing unit coupled to a second video memory, wherein said second video memory further includes a second frame buffer containing a second subset of said filtered data; and a temporary buffer, coupled to said first frame buffer and said second frame buffer each via a symmetric communication link, wherein said second graphics processing unit pushes content from a first portion of said second frame buffer to a first memory block of said temporary buffer, said first graphics processing unit pushes content from a second portion of said first frame buffer to a second memory block of said temporary buffer, said first graphics processing unit pulls and blends said content from said first memory block of said temporary buffer with content in a first portion of said first frame buffer; and said second graphics processing unit, in parallel with said first processing unit, pulls and blends said content from said second memory block of said temporary buffer with content in a second portion of said second frame buffer.
