UC/OS II (micro control operation systemtwo) is a ROM-based, customizable, preemptible, and real-time multi-task kernel with high portability, it is particularly suitable for microprocessor and controller, and is a real-time operating system (RTOs) with the same performance as many commercial operating systems ). To provide the best porting performance, uC/oⅱ uses ANSI to the maximum extent.C language development, and has been transplanted to more tha
After the OS initialization function osinit is executed, you can call the ostaskcreate or ostaskcreateext functions to create user tasks. These two functions are used by the kernel to create tasks and cannot be modified, therefore, it is called a system service. The user task program is written as a function and is called a user function. It has a line with the services provided by the operating system. Obviously, you must pass the User Function addre

-the-shelf instruction set, and multi-level flow, therefore, the computation performance is quite powerful and has been widely used in communication equipment, image processing, medical instruments, and other fields.In C6711, there are three types of interruptions: reset, unshielded interrupt (NMI), and shielded interrupt (INT4-INT15 ). The CSR registers control the global enable and enable the IER registers separately. There is no soft interrupt mechanism in C6711, so the

It took me two nights to finish reading "software technology", which should be a non-technical computer book that I once again applauded after "programmer's Cultivation". Although it was just a waste of time, however, the problem solved my doubts. Software Engineering emphasizes the process of software development, while soft
Original address: http://blog.csdn.net/imtgj/article/details/7107489? Reload In view of the recent issues related to CPU usage that involve the scheduling algorithm of Linux kernel, it is necessary to understand. Therefore, I wrote this article. Common Linux tasks include real-time tasks and non-real-time tasks. The scheduling algorithm of real-time tasks is familiar to priority preemption or priority preemption and time slice. The main idea is to give priority to efficiency. The Scheduling Alg
The first version of each software project is beautiful. The new project starts from scratch and all content is newly developed. Because of all-new development, there is no historical burden. The first version has very few bugs. Of course, programmers also try their best to do their best. This means that in the eyes of developers, the first version can be regarded as perfect: the code is beautiful, the design is good, and the architecture is excellent

to evaluate the anti-virus software only by the speed of virus-checking. The speed of anti-virus software is mainly related to engine and virus characteristic database. For example, an antivirus software can kill 100,000 viruses, another anti-virus software can only kill 100 viruses. Antivirus
First, when the task is running, it is used to save some local variables; Second, when a task is suspended, it is responsible for saving the running scene of the task, that is, the value of the CPU register. The stack is used to save local variables. In essence, the CPU register value is saved to ram. In UCOS, each task
OverviewRecently this time in strengthening the stability and reliability of the log system itself, a stable and reliable system can not be separated from the monitoring, we talk about the monitoring in addition to the survival of the service and the core Metrics collection and capture of these components, for which we have made the task of scheduled tasks to execute. Because of the general idea and design has been formed, so today to share the log sy
new features have been introduced in FreeRTOS version V8.2.0: task notifications. In most cases, task notifications can replace binary semaphores, Count semaphores, event groups, and can replace queues of length 1 (which can hold a 32-bit integer or pointer value), and task notifications are faster and use less RAM!

1. Project Design The dominant idea of project design can be understood as two types: full design and simple design. Full Design refers to investigating various aspects of the software before writing specific code, analyzing detailed requirements, and compiling all development documents, after all the procedures are designed, write the code again. In other words, after all the plans are completed, we can see the final view and start the war again. Thi
