vcgencmd measure_temp是用于获取树莓派CPU温度的系统命令。 res.replace("temp=","").replace("'C\n","")用于处理输出结果,去掉多余的字符串。 获取CPU占用率 获取CPU占用率需要使用psutil库提供的函数。 defget_cpu_usage():returnpsutil.cpu_percent(interval=1) 1. 2. 代码解释: psutil.cpu_percent(in...

在这个类的实例上调用measure_usage()时,它将进入一个循环,每0.1秒测量一次内存使用情况。将跟踪内存使用量的任何增加,并在循环退出时返回最大内存分配。 但是什么告诉循环退出呢?我们在哪里调用被监视的代码?我们在单独的线程中完成。 代码语言:javascript ...

. After waking up, the device context is restored in the critical zone. At this time, the interrupt flag for this interrupt is stored in the interrupt controller, but it is not executed. After the peripheral resumes, the CPU exits the critical zone, and the ISR of the interrupt will ...
From the console, you can use the time command (on UNIX systems) to measure memory usage and CPU user time. Make sure you have at least 5GB of free memory before executing the following:Shell $ time -f "Memory used (kB): %M\nUser time (seconds): %U" python3 naive.py Memory ...
