对于一个软件的编制人员来说,了解程序运行所耗费的时间是很有必要的。因为在某些控制系统中对时间有严格的要求,有必要将运行的时间限制在允许的范围之内。如运行超过了规定的时间,则需采取精简程序的办法,或是采用速度更快的语言来编程。当然也可以从硬件上来想办法,如提高晶 For a software compiler, to understand the time it takes to run the program is necessary. Because of the strict time requirements in some control systems, it is necessary to limit the operation time to within the allowable range. If run for longer than the specified time, you need to take the program to streamline, or faster language programming. Of course, you can find ways from the hardware, such as improving the crystal
