rtos programming

RTOs is a real-time operating systemLinux is a time-division system, but can be changed into a real system by configuring the kernel time-sharing operating system English: time-sharing Operating system Explanation: An operating system that enables a single computer to serve several, dozens of, or even hundreds of users at the same time. To connect the computer with many end users, the time-sharing operating system will change the system processor

The 4th Chapter RTOs the SMP expansion design and realizes the single core RTOs SMP expansion, needs to solve the system initialization, the task scheduling, the CPU synchronization and mutually exclusive, as well as the interrupt processing and so on aspect question, this article will propose the corresponding solution for these problems, and carries on the SMP extension realization on the uc/os-ii. 4.1 Sy

these two functions as empty. Both of these functions are commented out So what we're going to do now is find the two functions defined in the UCOS-III source, openOS_CPU_C.Cfile, see the source CustomSystick_handlerThe function is namedOs_cpu_systickhandler, change its name toSystick_handler。 As shown in the following illustration: Open it"Os_cpu_a.s"file, see the source CustomPendsv_handler functionis namedOs_cpu_pendsvhandler, change its name toPendsv_handler, and then change the declaration

4.3 Support SMP scheduling module design 4.3.1 Dispatch module function in the SMP system CPU does not master and slave, the operating system of the scheduling module to the CPU management is not through a dedicated CPU centralized management, but

4.4 SMP-enabled interrupt module design in SMP environment if all external interrupts are handled by one CPU, the interrupt response time of SMP system is still the level of single core processor. So the SMP hardware platform is either binding the

Chapter 5th Time Service 5.1 Time Service OverviewIn Sys/bios and Xdctools, there are several modules involved in clocking and clocking-related services: Ti.sysbios.knl.Clock module:Responsible for periodic system ticks that the kernel uses to hold

kernel, or the development of their own kernel, need to carefully consider. According to insiders, Huawei's Liteos is to choose the mature t-kernel kernel.If you have enough innovation to provide users with value that others cannot provide, then you can make a kernel of your own, like Djyos. Otherwise, you can use a mature kernel, like Huawei's Liteos. Operating system development, should focus on the integration of operating system extension features, in order to adapt to the development of th

I have been engaged in pythonWeb development for a year. Now I am confused. I mainly work on curd, that is, how to obtain data, and then present it to the front-end page. The framework uses django, optimization means adding memecache. Pay attention to this when querying the database. Currently, there are a lot of tangled issues: 1: the programming of process threads, how to use it in practice 2: network programmin
