    摘要： A system, method and computer program product for sampling computer system performance data are provided. The system includes a sample buffer to store instrumentation data while capturing trace data in a trace array, where the instrumentation data enables measurement of computer system performance. The system further includes a sample interrupt generator to assert a sample interrupt indicating that the instrumentation data is available to read. The sample interrupt is asserted in response to storing the instrumentation data in the sample buffer.

    摘要： The present invention relates to a method, computer program product and system for generating a sample signal from differing clock domain boundaries. The system comprises a cycle base component, a sample offset component being configured to receive a time-based sample pulse signal, and logic to generate a sample pulse. The sample pulse generation logic is configured to receive a time-based sample pulse signal, a free running counter value, a sample offset counter value, and deliver a sample pulse signal.

    摘要： A system, method and computer program product for event-based sampling to monitor computer system performance are provided. The system includes a sample buffer to store a sample of instrumentation data, where the instrumentation data enables measurement of computer system performance. The system also includes a sample segment selector to isolate a segment of the sample of instrumentation data as an event. The system further includes an instrumentation counter counting in response to a combination of the event and a sample pulse, and asserting a sample interrupt indicating that the sample of instrumentation data is ready to logout from the sample buffer.
