Methods, apparatus, systems, and articles of manufacture are disclosed to implement predictor prefetching in video encoding. The example apparatus includes processor circuitry to perform operations to instantiate a predictor list generator circuitry and a predictor prefetch circuitry. The example predictor list generator circuitry to obtain predictor candidates indicating memory locations storing reference blocks from a previous block and sort the predictor candidates in a priority order. The example predictor prefetch circuitry to send cache line requests to the memory corresponding to at least some the predictor candidates that satisfy a threshold priority value. The example predictor prefetch circuitry to send the cache line requests to the memory before a reference block winner of the previous block is determined.

Methods and apparatus to implement predictor prefetching in video encoding

One embodiment provides for a graphics processing unit comprising a processing cluster to perform multi-rate shading via coarse pixel shading and output shaded coarse pixels for processing by a post-shader pixel processing pipeline.

Fragment compression for coarse pixel shading

One embodiment provides for a graphics processing unit comprising a processing cluster to perform coarse pixel shading and output shaded coarse pixels for processing by a pixel processing pipeline and a render cache to store coarse pixel data for input to or output from a pixel processing pipeline.

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.
