    • Disclosed are methods and apparatus for measuring performance of a multi-thread processor. The method and apparatus determine loading of a multi-thread processor through execution of an idle task in individual threads of the multi-thread processor during predetermined time periods. The idle task is configured to loop and run when no other task is running on the threads. Loop executions of the idle task on each thread are counted over each of the predetermined time periods. From these counts, loading of each of the threads of the multi-thread processor may then be determined. The loading may be used to develop a processor profile that may then be displayed in real-time.
    • 公开了用于测量多线程处理器的性能的方法和装置。 该方法和装置通过在预定时间段内通过在多线程处理器的各个线程中执行空闲任务来确定多线程处理器的加载。 空闲任务被配置为在线程上没有其他任务运行时循环和运行。 每个线程上的空闲任务的循环执行在每个预定时间段内被计数。 从这些计数,可以确定多线程处理器的每个线程的加载。 可以使用加载来开发可以实时显示的处理器简档。
