Latest Patents

Among his latest patents is a method and apparatus for clearing hazards using jump instructions. This invention describes a technique 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 instruction hazards that preceded the jump instruction. Alternatively, the hazard logic can 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 optimal performance.

Another significant patent is the method and apparatus for binding shadow registers to vectored interrupts. This invention provides a system for associating shadow register sets with interrupt routines. It includes a vector generator that receives interrupts and generates exception vectors to call the corresponding interrupt routines. The exception vector takes into account the type and priority level of the interrupt when selecting the appropriate vector. The shadow set mapping logic is coupled to the vector generator and contains programmable fields that correspond to different exception vectors. When an interrupt occurs, the vector generator generates a corresponding exception vector, and the mapping logic retrieves the data to switch to the appropriate shadow register set for use by the interrupt routine.
