With a total of 2 patents to his name, Jeppesen's work has had a considerable impact on the efficiency of pipeline microprocessors.

Latest Patents

One of Jeppesen's latest patents is titled "Method and apparatus for clearing hazards using jump instructions." This invention describes a method and apparatus for overlaying hazard clearing with a jump instruction within a pipeline microprocessor. The apparatus includes hazard logic that detects when a jump instruction specifies that hazards are to be cleared as part of a jump operation. If hazards are to be cleared, the hazard logic disables branch prediction for the jump instruction, allowing it to proceed down the pipeline until it is resolved, while flushing the pipeline behind it. This effectively clears all execution and/or instruction hazards that preceded the jump instruction. Alternatively, the hazard logic can cause issue control logic to stall the jump instruction for a specified number of cycles until all hazards are cleared. State tracking logic may also be included to determine if any instructions are executing in the pipeline that create hazards, ensuring that the hazard logic performs optimally.
