Abstract
Methods and apparatus for subdividing a shader program into regions or 'phases' of instructions identifiable by phase identifiers (IDs) inserted into the shader program are provided. The phase IDs may be used to constrain execution of the shader program to prohibit texture fetches in later phases from being executed before a texture fetch in a current phase has completed. Other operations (e.g., math operations) within the current phase, however, may be allowed to execute while waiting for the current phase texture fetch to complete.
