Techniques to dispatch threads of a graphics kernel for execution to increase the interval between dependent threads and the associated are disclosed. The dispatch interval may be increased by dispatching associated threads, followed by threads without any dependencies, followed by threads dependent on the earlier dispatched associated threads. As such, the interval between dependent threads and their associated threads can be increased, leading to increased parallelism.

Thread dispatching for graphics processors

Techniques related to entropy coding with look-up-table based probability updating for video coding including setting a search range for candidate probabilities. This also involves selecting one of the candidate probabilities of the look-up table to update a previous probability for coding of a symbol, and selecting based on, at least in part, the bit-cost associated with updating the previous probability with at least one of the candidate probabilities.

Method and system of entropy coding using look-up table based probability updating for video coding

Described herein are technologies related to enforcing thread dependency using a hybrid scoreboard. An encoded video information that includes a plurality of threads is received, a first set and a second set of threads from the plurality of thread is determined, the first and second sets of threads are assigned to a hardware and a software, respectively, and dependency threads in the first and second sets of threads is enforced.

Power efficient hybrid scoreboard method

Systems, apparatus and methods are described including operations for graphics processing including spatial variant dependency pattern processing for GPU based intra prediction.

Spatial variant dependency pattern method for GPU based intra prediction in HEVC

Techniques to saturate a graphics processing unit (GPU) with independent threads from multiple kernels are described. An apparatus may include a graphics processing unit driver for a graphics processing unit having a first partition including a first plurality of execution units and a second partition including a second plurality of execution units, the graphics processing unit driver to dispatch one or more threads of a first kernel to the first partition and to dispatch one or more threads of a second kernel to the second partition to increase a utilization of the plurality of execution units and avoid hardware resource competition.

Independent thread saturation of graphics processing units

A rate control method comprises determining a target buffer fullness for each frame of a plurality of frames, obtaining a real buffer fullness for a previous frame of the plurality of frames; determining a target allocation for a current frame based on the real buffer fullness and target buffer fullness for the previous frame, wherein at least two frames of the plurality of frames have different target buffer fullness.
