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 17957978 titled 'DEVICE, METHOD, AND SYSTEM TO DETERMINE A COUNT OF RETIRED PREFETCH INSTRUCTIONS
Simplified Explanation
The abstract of the patent application describes techniques and mechanisms for a processor to determine the count of retired prefetch instructions. A Performance Monitoring Unit (PMU) monitors instruction execution, detects retired prefetch instructions, and updates a count accordingly. The PMU also distinguishes non-prefetch instructions to prevent count updates.
- Processor uses a Performance Monitoring Unit (PMU) to monitor instruction execution

Unanswered Questions
How does the PMU detect the retirement of prefetch instructions?
The abstract mentions that the PMU detects the retirement of prefetch instructions, but it does not specify the exact mechanism or technique used for this detection.
What impact does updating the count of retired prefetch instructions have on processor performance?
While the abstract describes the updating of the count based on retired prefetch instructions, it does not discuss the potential implications or effects of this process on overall processor performance.
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.
