摘要： Embodiments include an apparatus, a computer readable medium and a method for distributing tessellations within an accelerated processing device (APD) including at least two compute units. Embodiments include processing a plurality of patches in a first compute unit using a hull shader to generate hull shader output data. Once generated, hull shader output data is stored to an off-chip memory when tessellation factors associated with the shader program are greater than a configured threshold. Once stored in the off-chip memory, at least a portion of the hull shader output data is dynamically processed using a second compute unit.

摘要： Methods are disclosed for improving data processing performance in a processor using on-chip local memory in multiple processing units. According to an embodiment, a method of processing data elements in a processor using a plurality of processing units, includes: launching, in each of the processing units, a first wavefront having a first type of thread followed by a second wavefront having a second type of thread, where the first wavefront reads as input a portion of the data elements from an off-chip shared memory and generates a first output; writing the first output to an on-chip local memory of the respective processing unit; and writing to the on-chip local memory a second output generated by the second wavefront, where input to the second wavefront comprises a first plurality of data elements from the first output. Corresponding system and computer program product embodiments are also disclosed.

摘要： A system, method and a computer program product are provided for distributing prim groups for parallel processing in a single clock cycle. A work distributor divides a draw call for primitive processing into a plurality of prim groups according to a prim group size. The work distributor then distributes the plurality of prim groups to a plurality of shader engines for parallel processing of the plurality of prim groups during a clock cycle. The size of a prim group and a number of prim groups are scaled to the plurality of shader engines.
