Abstract: A GPU may be configured to detect and nullify unnecessary instructions. Nullifying unnecessary instructions include overwriting a detected unnecessary instruction with a no operation (NOP) instruction. In another example, nullifying unnecessary instructions may include writing a value to a 1-bit instruction memory. Each bit of the 1-bit instruction memory may be associated with a particular instruction of the draw call. If the 1-bit instruction memory has a true value (e.g., 1), the GPU is configured to not execute the particular instruction.

Abstract: Techniques are described to perform a shuffle operation. Rather than using an all-lane to all-lane cross bar, a shuffler circuit having a smaller cross bar is described. The shuffler circuit performs the shuffle operation piecewise by reordering data received from processing lanes and outputting the reordered data.

Abstract: Techniques are described in which an indication is included to indicate a last use of an intermediate value generated as part of determining a final value is not be stored in a general purpose register (GPR). A processing unit avoids storing the intermediate value in the GPR based on the indication because the intermediate value is no longer needed for determining the final value.
