Abstract
A graphics processing unit has a reduced memory space shadow memory as a source of state information for performing validation of commands. The reduced memory space shadow memory is smaller in size than a full version of state variables associated with an abstract state machine representation of a class of commands received from a software driver. The reduced memory space shadow memory is used by validation logic to detect exceptions indicative of an illegal command or sequence of commands.
