Abstract:
Embodiments for programming a graphics pipeline, and modules within the graphics pipeline, are detailed herein. Several of these embodiments utilize offset registers associated with the instruction tables for the modules within the pipeline. The offset register serves as a pointer to locations in the instruction table, which allows instructions to be written to be instruction table, without requiring that the shader programs have explicit addresses. One embodiment describes a method of programming a graphics pipeline. This method involves accessing the shader program stored in memory. A shader instruction is generated from this shader program, and loaded into an instruction table associated with a target module graphics pipeline. The shader instruction is loaded into the instruction table at the location indicated by an offset register.
