BREAKING THE FRAMEBUFFER BOTTLENECK : THE CASE FOR LOGIC-ENHANCED MEMORIES

A central problem in designing interactive graphics systems is the bandwidth bottleneck between the rasterizer, the engine that computes pixel values for each primitive in a scene, and the frame buffer, the memory system that stores pixel values. Despite remarkable advances in semiconductor storage, this problem not only is still with us, but increasingly is the barrier to further improvements in interactive systems. Current highend graphics systems are approaching performance limits imposed by the design of commercial DRAMs.
