摘要： A method of acquiring software profile information of a target software application includes receiving a programmed interrupt while executing an application in a computer system, servicing the interrupt such that call stack information is acquired and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. Some or all of the call stack information may be recorded. The statistical information includes statistics concerning the number of samples wherein a series of functions calls are included in the call stack information and the number of samples wherein a set of function calls are at the top of the call stack information.
摘要翻译：获取目标软件应用的软件简档信息的方法包括：在计算机系统中执行应用程序时接收编程的中断，为中断提供服务，从而获取调用堆栈信息，并处理调用堆栈信息以产生关于功能调用的统计信息。调用堆栈信息包括从目标应用程序以及操作系统导出的程序计数器和其他信息。可以记录部分或全部呼叫堆栈信息。统计信息包括关于调用堆栈信息中包括一系列函数调用的样本数的统计信息，以及其中一组函数调用位于调用堆栈信息的顶部的样本数。

摘要： A method of acquiring software profile information of a target software application includes Monitoring an application program for system calls, detecting a system call of interest to the user, acquiring stack information, and processing the call stack information to produce statistical information concerning function calls. The call stack information includes program counter and other information which is derived from the target application as well as operating system. The call stack information may be recorded. The statistical information includes statistics concerning the number of samples that any one function call is at a top of the call stack information, the number of samples that a series of functions calls are included in the call stack information, and the number of samples that a set of function calls are at the top of the call stack information.
摘要翻译：获取目标软件应用程序的软件简档信息的方法包括：监控系统调用的应用程序，检测用户感兴趣的系统调用，获取堆栈信息，以及处理调用堆栈信息以产生有关功能调用的统计信息。调用堆栈信息包括从目标应用程序以及操作系统导出的程序计数器和其他信息。可以记录呼叫堆栈信息。统计信息包括关于任何一个功能调用在调用堆栈信息的顶部的样本数量，一系列函数调用的样本数被包括在调用堆栈信息中的统计信息，以及一组函数调用位于调用堆栈信息的顶部。
