| 20090295820 | Redundancy Method and Apparatus for Shader Column Repair - A method and apparatus for shader data repair utilizing a Redundant Shader Switch (RSS). The RSS consists of an input and output section whereby when a defective shader pipe is detected, the RSS multiplexes shader pipe data destined to the defective shader pipe to a redundant shader pipe array for processing. Once processed, the shader pipe data is multiplexed back to the RSS where the processed shader pipe data is directed to the corresponding output column of the RSS. The RSS contains delay pipes used to re-align and synchronize the repaired shader pipe data with output export data. | 12-03-2009 |
| 20090295821 | Scalable and Unified Compute System - A Scalable and Unified Compute System performs scalable, repairable general purpose and graphics shading operations, memory load/store operations and texture filtering.
