Abstract: Methods and apparatus relating to Multi-Sample Anti-Aliasing (MSAA) memory bandwidth reduction for sparse sample per pixel utilization are described. In an embodiment, Multi-Sample Anti-Aliasing (MSAA) logic generates render subspan plane information based on data stored in a cacheline. One or more read operations to memory are suppressed based on a determination that the cacheline is in a clear state. Other embodiments are also disclosed and claimed.

Abstract: Methods, systems and apparatuses may provide for hardware sampler technology that determines mip region dimensions of a feedback map based on a description of the feedback map, identifies accessed texels in a texture based on a view of a resource that is paired with the feedback map, and records the accessed texels in the feedback map based on the mip region dimensions.

Abstract: Briefly, in accordance with one or more embodiments, a processor receives an incoming data stream that includes alpha channel data, and a memory stores an application programming interface (API). The API is to route the alpha channel data to a fixed point blending unit to perform one or more blending operations using fixed point representation of the alpha channel data. The API is further to route the incoming data stream to a floating point blending unit to perform operations involving floating point representation of the incoming data.
