Graphics Processing Apparatus Bypassing Shading Processor for Power Reduction

A reorder buffer is introduced as an intermediary component between the texturing processor and the color/depth blending processor. The reorder buffer receives data from the texturing processor that has bypassed the shading processor, and buffers this data in the correct processing order before forwarding it to subsequent stages. This mediator ensures that data processing order is maintained even when the texturing processor directly performs post-processing operations without involving the shading processor, thus enabling power reduction while preserving data integrity.

The system implements dynamic processing paths that can be configured based on operational requirements. The texturing processor can selectively bypass the shading processor when performing post-processing operations, and the reorder buffer dynamically manages data flow between different paths. This dynamic configuration allows the system to optimize for performance when needed while maintaining the ability to use traditional paths when appropriate, balancing productivity gains with controlled complexity through conditional path selection rather than permanently fixed multiple paths.
