Included are embodiments of systems and methods for processing metacommands. In at least one exemplary embodiment a Graphics Processing Unit (GPU) includes a metaprocessor configured to process at least one context register, the metaprocessor including context management logic and a metaprocessor control register block coupled to the metaprocessor, the metaprocessor control register block configured to receive metaprocessor configuration data, the metaprocessor control register block further configured to define metacommand execution logic block behavior. Some embodiments include a Bus Interface Unit (BIU) configured to provide the access from a system processor to the metaprocessor and a GPU command stream processor configured to fetch a current context command stream and send commands for execution to a GPU pipeline and metaprocessor.
