Tile-Based Graphics Primitive State Commands for Flexible Data Storage

The patent applies universality by designing a single variable state command type that can store multiple different types of state data (e.g., blend factors, alpha test values, depth values) through a unified command structure. This replaces the need for separate dedicated command types for each state data type, thereby reducing command type diversity while maintaining complete data storage capability.

The patent utilizes parameter changes by implementing a variable command format where the structure and interpretation of the command depend on the specific state data being stored. The command includes a state data type identifier and variable-length payload that adapts to the requirements of different state parameters, allowing one command type to handle multiple data types through parameter variation rather than requiring separate fixed command types for each.

The patent implements parameter changes by creating a variable command format where the command structure adapts to the specific state data being stored. The command includes a state data type identifier that specifies the format of the following payload, allowing the command to be compact for simple states (e.g., single float) but expand only when necessary for complex states. This eliminates the need for overly complex fixed formats while maintaining storage efficiency through conditional structure expansion.

The patent applies segmentation by dividing the command into distinct functional components: a command header identifying the state data type, and a variable-length payload containing the actual state data. This segmentation allows the command to be efficiently parsed and processed while maintaining flexibility in the payload size and structure based on the specific state data requirements, improving storage efficiency without increasing overall command complexity.

The patent applies local quality by implementing selective state data storage where only the necessary state data is stored and processed for each primitive based on its specific requirements. Different primitives or groups of primitives can have different state data stored according to their rendering needs, rather than uniformly storing all possible state data for every primitive. This reduces processing overhead for simple primitives while maintaining complete processing capability when needed.

The patent utilizes partial action by storing and processing only the essential state data required for each primitive's rendering, rather than storing all possible state data. The variable command format allows the system to store minimal necessary information (e.g., only blend factors when needed, or only alpha test values when required), thereby improving processing efficiency by reducing unnecessary data handling while maintaining processing completeness for the actual rendering operations.
