摘要： A high level shader language compiler incorporates transforms to optimize shader code for graphics processing hardware. An instruction reordering transform determines instruction encapsulations of dependent instructions that reduce concurrent register usage by the shader. A phase pulling transform re-organizes the shader's instructions into phases that reduce a measure of depth of texture loads. A register assigning transform assigns registers to lower register usage by the shader.

摘要： A shader program capable of execution on a GPU is analyzed for constant expressions. These constant expressions are replaced with references to registers or memory addresses on the GPU. A preshader is created that comprises two executable files. The first executable file contains the shader program with the each constant expression removed and replaced with a unique reference accessible by the GPU. The first file is executable at the GPU. A second file contains the removed constant expressions along with instructions to place the values generated at the associated reference. The second executable file is executable at a CPU. When the preshader is executed, an instance of the first file is executed at the GPU for each vertex or pixel that is displayed. One instance of the second file is executed at the CPU. As the preshader is executed, the constant expressions in the second file are evaluated and the resulting intermediate values are passed to each instance of the first file on the GPU.

摘要： Usage semantics allow for shaders to be authored independently of the actual vertex data and accordingly enables their reuse. Usage semantics define a feature that binds data between distinct components to allow them to work together. In various embodiments, the components include high level language variables that are bound by an application or by vertex data streams, high level language fragments to enable several fragments to be developed separately and compiled at a later time together to form a single shader, assembly language variables that get bound to vertex data streams, and parameters between vertex and pixel shaders. This allows developers to be able to program the shaders in the assembly and high level language with variables that refer to names rather than registers. By allowing this decoupling of registers from the language, developers can work on the language separately from the vertex data and modify and enhance high level language shaders without having to manually manipulate the registers. This also allows the same shaders to work on different sets of mesh data, allowing the shaders to be reused. Generally, semantics can be used as a data binding protocol between distinct areas of the programmable pipeline to allow for a more flexible workflow.
