摘要： Systems and methods of enabling virtual calls in a single instruction multiple data (SIMD) environment may involve detecting a virtual call of a function and using a single dispatch of the function to invoke the virtual call for two or more channels of the virtual call. In one example, it is determined that the two or more channels share a common target address and a single dispatch of the function is conducted with respect to the common target address. The process may be iterated for additional channels of the virtual call that share a common target address.

摘要： A processing apparatus is described. The apparatus includes a graphics processing unit (GPU), including a plurality of execution units to process graphics context data and a register file having a plurality of registers to store the graphics context data; and register renaming logic to facilitate dynamic renaming of the plurality of registers by logically partitioning the plurality of registers in the register file into a set of fixed registers and a set of shared registers.

摘要： Reducing SIMD fragmentation for SIMD execution widths of 32 or even 64 channels in a single hardware thread leads to better EU utilization. Increasing SIMD execution widths to 32 or 64 channels per thread, enables handling more vertices, patches, primitives and triangles per EU hardware thread. Modified 3D pipeline shader payloads can handle multiple patches in case of domain shaders or multiple primitives when primitive object instance count is greater than one in the case of geometry shaders and multiple triangles in case of pixel shaders.

摘要： To use SIMD lanes efficiently for domain shader execution, domain point data from different domain shader patches may be packed together into a single SIMD thread. To generate an efficient code sequence, each domain point occupies one SIMD lane and all attributes for the domain point reside in their own partition of General Register File (GRF) space. This technique is called the multiple-patch SIMD dispatch mode.
