DEVICE, METHOD, AND SYSTEM TO DETERMINE A COUNT OF RETIRED PREFETCH INSTRUCTIONS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240111656 titled 'DEVICE, METHOD, AND SYSTEM TO DETERMINE A COUNT OF RETIRED PREFETCH INSTRUCTIONS
Simplified Explanation
The patent application describes techniques and mechanisms for a processor to determine the count of retired prefetch instructions. The processor includes a performance monitoring unit (PMU) that monitors the execution of an instruction sequence by a core of the processor. The PMU detects the retirement of a prefetch instruction and updates a count of retired prefetch instructions. It also distinguishes between prefetch and non-prefetch instructions to prevent updating the count incorrectly.
- Performance monitoring unit (PMU) monitors instruction execution

Original Abstract Submitted
techniques and mechanisms for circuitry of a processor to determine a count of prefetch instructions which have been retired, or are designated for retirement. in an embodiment, a performance monitoring unit (pmu) monitors the execution of an instruction sequence by a core of said processor. the pmu detects the retirement of a first instruction, and further makes a first determination that the instruction is of a prefetch instruction type. based on the first determination, counter circuitry of the processor updates a count of one or more instruction retirements, wherein each such retired instruction is of the prefetch instruction type. the pmu further makes a second determination that another retired second instruction is of a non-prefetch instruction type. in another embodiment, the counter circuitry prevents any updating of that same count based on the second determination.
