This is shown for various grain sizes, plat-forms, tick frequencies, and OSs. To eliminate such noise, we suggest replacing ticks with an alternative mechanism we call “smart timers”.

An accounting group accumulates the CPU usage of all of its child groups and the tasks directly present in its group.

WebbThe frequency of the RTOS tick interrupt. The tick interrupt is used to measure time. Therefore a higher tick frequency means time can be measured to a higher resolution. However, a high tick frequency also means that the RTOS kernel will use more CPU time so be less efficient. The RTOS demo applications all use a tick rate of 1000Hz.
