如何计算处理器在应用程序中执行多行所花费的时间？

喜
我试图在应用程序中利用中断的优势。
但是，我发现当处理器在中断处理程序代码中运行行时，它会错过其他一些中断信号。
由于这些中断信号是由VHDL模块创建的，即使中断事件已经处理，它们也不会停止。
在中断处理程序代码中，我必须在处理中断事件之前重置全局中断信号。
所以我必须知道中断处理程序在处理中断事件期间需要多长时间。
有人能告诉我如何计算处理器在应用程序中执行多行所花费的时间吗？
感谢您的考虑和帮助！

hi, I tried to take the advantage of the interrupt in an application. However, I found when the processor run the lines in the interrupt handler code, it missed some other interrupt signals.  Since these interrupt signals were created by a VHDL module, and they woundn't be stopped even when the interrupt event has been processing. While in the interrup handler code, I have to reset the global interrupt signals before processing the interrupt event.  So I have to know how long the interrupt handler would take during it processed the interrupt event.  Could anybody tell me how to calculate the time that the processor spent for executing several lines in an application? Thank you for your consideration and help!
