Top is the most common command to view CPU usage under Linux, which is powerful and easy to use. But one thing is very bad, is top's working state is full screen, and cannot return. It's hard to get CPU utilization if you want to call the top command in a C program.
So we need a simplified version of top.

with the hardware platform. A constant Hz is defined in the system, representing the number of minimum time intervals per second. In this way, the unit of jiffies is 1/Hz. Jiffies of Intel Platform is measured in 1/100 seconds, which is the minimum time interval that the system can distinguish. For each CPU time slice, jiffies must be added with 1. CPU utilization is expressed by dividing the execution use
