工作学习 / 专业技术讨论 / 急！做Linux的朋友请帮忙。我想参考TOP命令做嵌入式系统cpu性能分析。哪位能帮我传个TOP命令的源代码到我信箱：thanku99@gmail.com。或告诉我在linux包的什么目录下可找到（我没安装linux)。谢了先！

top is complex. I wrote one before. It is rather easy. 3 days of work. I suggest you google for some idea then write one yourself. Sorry. I cannot give the code to you, because it is property.

Thanks. The problem is I have no idea what algorithm it is. Actually,some basic performance data like CPU load, tasks' CPU utilizationwould be enough. Appreciated if you could give me some idea or simple formula!

Top is complicated because the kernel of the system do most of the job.

Another problem is all these tools is quite OS-specific.

Check you email. The best way you need to have a Linux/FreeBSD environment to see how it works. Enjoy coding.
