1 IntroductionMultimedia frameworks are very important and important modules. Especially in Android systems, it is necessary to understand the multimedia playing effect.The scheduling problem in multimedia is a story behind it, but it has a crucial impact on the performance. This article does not fully analyze the Multimedia Framework and aims to explore the differences between the scheduling of media frame

Starting from this blog, we will go deep into process management and even the core concept of the entire kernel-process scheduling. Here, let's take a look at the relevant concepts. We have just started to talk about Linux. It is a time-sharing system, but it has the characteristics of a real-time system. So like any time-sharing system, a quick switch from one process to another achieves the magical effect of simultaneous execution of multiple proce

I. kernel Overview:In a multi-task system, the kernel is responsible for managing tasks, or allocating CPU time for each task, and communicating between tasks. The basic service provided by the kernel is task switching. The use of the Real-Time Kernel greatly simplifies the design of the application system because the real-time kernel allows applications to be divided into several tasks and managed by the real-time kernel. The kernel itself also increases the application load, the code space inc

Experiment Three Process Scheduling Simulation program 2.0First, the purpose of the experimentA process scheduler is completed in a high-level language to deepen the understanding of process concepts and process scheduling algorithms.Second, the experimental requirementsDesign a process scheduling simulator with n processes executing concurrently.1.

Summary of scheduling and running principles for processes, threads, and co-routines.Introduction to scheduling policies for processes and threadsLinux operating system detailed scheduling policy can be consulted: http://blog.csdn.net/gatieme/article/details/51872659There are three main scheduling strategies in Linux:

OverviewThis question is the interview often ask questions, at that time to hear the feeling is too broad, a little big, in the heart know but say not all, here to do a summaryThe role of the "1" process scheduling"2" Scheduling Germany policy1, the role of process scheduling, process scheduling is the process of

Introduction of three operating modes and 10 scheduling algorithms of LVSWorking Mode Introduction:1.Virtual server via NAT (Vs-nat)Advantage: Physical servers in a cluster can use any TCP/IP-enabled operating system, the physical server can allocate reserved private addresses for the Internet, and only the load balancer needs a legitimate IP address.Cons: Limited scalability. When the server node (normal PC server) data grows to 20 or more, the load
