Graphics Pipeline Fragment Data Verification Comparator

The patent segments the graphics processing pipeline into multiple independent verification stages: vertex data transformation verification, texture mapping verification, fragment processing verification, and output buffer verification. Each stage has dedicated verification logic that operates independently, allowing fault detection without compromising the parallel processing performance of the GPU.

The patent introduces intermediary verification units between processing stages that act as mediators. These units include vertex data verification logic between the vertex shader and rasterizer, texture verification logic between texture sampling and fragment shader, and buffer verification logic between rendering operations and output. These intermediaries verify data integrity without becoming performance bottlenecks.

The patent implements preliminary verification actions at the beginning of each processing stage. Vertex data integrity is verified before transformation, texture data is validated before sampling, and buffer states are checked before rendering operations. This preliminary verification prevents faulty data from propagating through the pipeline without adding significant complexity to the core processing units.

The patent establishes feedback mechanisms where verification results from each processing stage are fed back to control subsequent operations. If verification fails at any stage, the system generates error signals that trigger appropriate responses such as rendering alternative content or halting processing, ensuring functional safety without requiring complex redesign of the entire GPU architecture.
