Latest Patents
One of his latest patents is titled "Flag renaming and flag masks within register alias table." This invention presents a mechanism and method for renaming flags within a register alias table (RAT) to increase processor parallelism. It also provides and utilizes flag masks associated with individual instructions to reduce data dependencies between concurrently processed instructions. The RAT unit offers register renaming to create a larger physical register set, thereby eliminating false data dependencies that can hinder superscalar processing performance. The renamed flag registers contain multiple flag bits, which can be updated or read by different instructions. Additionally, static and dynamic flag masks are associated with specific instructions, indicating which flags can be updated and which are actually updated during instruction execution.
Another significant patent by Bajwa is the "Method and apparatus for changing flow of control in a processor." This invention simplifies the handling of instruction control flow changes in a microprocessor. Instead of implementing a change in instruction flow immediately, the processor first recognizes the need to redirect flow from a predicted instruction path to the correct one, based on a flow control indicator. This indicator can be attached to instructions or inserted as a separate instruction in the pipeline. The pipeline is then cleared of any erroneous instructions that do not follow the correct flow, allowing for a more efficient processing sequence.
