9. The method of claim 6 , wherein said semantic processing comprises semantic processing and parsing to organize validation checks to reduce shadow memory requirements.
6. A method of designing a graphics processing unit, comprising: receiving an abstract model of a graphics system having a class of commands and a set of state variables; and semantically processing said abstract model to generate validation logic for said class of commands utilizing a reduced memory space shadow memory having a memory size smaller than that of a memory size associated with storing a full representation of said set of state variables, wherein said semantic processing comprises semantic processing and parsing validation checks to determine a subset of said set of state variables required for validation.
