  • Performance monitoring based on instruction sampling in a microprocessor
    Patent number: 6748522
    Abstract: The problem identified above is addressed in large part by a microprocessor as disclosed herein. The microprocessor includes a dispatch unit configured to receive a set of instructions from an instruction cache and to forward the set of instructions to an issue queue when the instructions are ready for execution. The dispatch unit may include sampling logic that is configured to select one of the instructions for performance monitoring from the set of instructions. The microprocessor further includes a performance monitor unit enabled to monitor performance characteristics of the selected instruction as it executes. The sampling logic may identify the instruction selected for monitoring as the instruction occupying an eligible position within the set of instructions. The eligible position from which the monitored instruction is selected may vary with each subsequent set of instructions.
