Functions Overview

Each board has a CPU, and the operation of each board relies on the CPU.

CPU occupancy describes the usage status of the CPU during a certain period. CPU occupancy reflects the ration of non-idle time to total time. It can be expressed by the following formula:

CPU occupancy = (Total time - Idle time) / Total time

Idle time refers to time taken by the CPU to process the IDLE task. The IDLE task has a low priority and does not involve any specific operation. If the IDLE task is scheduled, the CPU is in the idle state.

Besides the total CPU occupancy, the CPU occupancy of each task can be calculated.

CPU occupancy of each task = Operation time of the task / Total time

The root directory is as follows:
