在具体介绍本申请实施例所提供的多媒体编辑方法的实现过程之前，下面先就本申请实施例涉及的部分计算机技术术语进行简要解释，以便更好地理解本申请方案。Before specifically introducing the implementation process of the multimedia editing method provided by the embodiment of the present application, some computer technical terms involved in the embodiment of the present application will be briefly explained below, so as to better understand the solution of the present application.
进程，是资源(CPU、内存等)分配的基本单位，应用程序运行时系统就会创建一个进程，并为它分配资源，然后把该进程放入进程就绪队列，进程调度器选中它的时候就会为它分配CPU时间，应用程序开始真正运行。其中，进程调度器用于调度和管理进程的运行，进程调度器的一个重要目标是有效地分配CPU时间，并且在面对一些互相冲突的进程任务时，既要为关键实时任务保障最小化响应时间、又要最大限度地提高CPU的总体利用率，以提供较好的用户体验。A process is the basic unit of resource (CPU, memory, etc.) allocation. When the application program is running, the system will create a process and allocate resources to it, and then put the process into the process ready queue. When the process scheduler selects it, it will CPU time is allocated to it, and the application starts to actually run. Among them, the process scheduler is used to schedule and manage the operation of the process. An important goal of the process scheduler is to effectively allocate CPU time, and when faced with some conflicting process tasks, it is necessary to minimize the response time for key real-time tasks. , but also to maximize the overall utilization of the CPU in order to provide a better user experience.
