Abstract:
Various embodiments enable low frequency calculation of derived uniform values. A compiler can identify one or more portions of a shader that calculate a derived value based on an input value. For example, this portion may include instructions that use constant values, or the results of prior functions that used constant values. The constant values may include hardcoded values provided by the program (e.g., immediates) and/or other constant values. This portion of the shader can be extracted by the compiler and compiled into a first program. The compiler can compile the remainder of the shader into a second program that receives the derived uniform values from the first program. By extracting the portion(s) of the program that calculates a derived value into a separate program, the derived uniform value or values can be calculated at a lower frequency than if they were calculated for each pixel.
