"abstract" in order to reduce the development difficulty of DSP system software, to ensure the real-time nature of the system, shorten the development cycle, the embedded real-time operating system Μc/os-ⅱ porting to the DSP chip is a common method at present. This paper introduces the characteristics of embedded real-time operating system (Μc/os-ⅱ), and analyzes the porting method of Μc/

In the μC/OS-ⅲ system, the task itself has five states. 1. sleep state After calling the function ostaskcreate () to create a task, the task can be managed by μC/OS-ⅲ. The job code in sleep state has actually been written into the code space, but μC/OS-ⅲ does not know its existence. When you do not need μC/OS-ⅲ to mana

Application of M16C62 in uC/OS-II embedded system 13:41:25: Preface With the development of micro-electronics technology and networks, people are increasingly familiar with networks. Network terminal products are getting more and more people's attention. The application of embedded operating systems has also gained unprecedented development, and people have made great progress in Embedded research. The Design and Application of a real-time and multi-t

Python system modules include sys, OS, glob, socket, threading, _ thread, queue, time, timeit, subprocess, Multiprocessing, signal, select, shutil, and tempfile. Most system-level interfaces are concentrated in the SYS and OS modules. The SYS module includes: Platform and version information, such as SYS. Platform, SYS. maxsize, SYS. Version Module search path SYS. Path Module table SYS. mod

supported; 64 priorities. You can only create 64 tasks. You can only create 56 tasks; Each task has different priorities. Priority reversal is not supported; The ready queue uses a memory ing table for fast query. High Efficiency; Supports clock beats; Supports semaphores, message queues, event control blocks, event flag groups, and message and email task communication mechanisms; Supports interruption nesting. The number of layers of interruption nesting can reach 255. the interruption

OS loader is a special type of EFI image. It is responsible for entering the system from the firmware environment into the OS environment. It has to complete the following important steps: 1. the OS loader must determine where the file is called, so that the OS loader can obtain other files from the same location. 2. t

The Chromium OS is an open source project for Google Chrome OS computer operating systems, which is provided for developers, and everyone can check, modify, or even compile their own version of the code. The operating system (OS) has become an essential part of our lives. A new operating system model that uses "cloud computing" to achieve most of the functionali

Python module OS, pythonos The OS module allows you to create, delete, and view file attributes for directories or files, as well as perform path operations on files and directories. For example: absolute path, parent directory ...... OS. sep can replace the path separator specified by the operating system. "\" In windows and "/" in Linux "/" The

I have translated and summarized it based on the technical documents of the iPhone Dev center. Reprinted please indicate the source: http://blog.csdn.net/zhyzh2046/ The iPhone OS consists of two parts: the operating system and the technology that can run native programs on the iPhone and iPod Touch devices. Because the iPhone is developed for mobile terminals, the user requirements to be addressed are somewhat different from those of Mac

Improve the real-time performance of IJLC/OS n and Il with coprocessor [Date: 2008-10-7] Source: single-chip microcomputer and Embedded System Application Author: Tsinghua University Feng Zedong Shao Beibei [Font:Large Medium Small] 　 IntroductionμC/OS-II supports a maximum of 63 tasks and multiple inter-process communication mechanisms such as semaphores, mailboxes, and message queues.

I haven't written a blog for a long time. Recently, the competition was one after another, so I had to participate in the competition. So the learning of stm32 has been stuck, and I started to learn ucosii from the time when I prepared the module recently, No way, you can continue learning .. Now, I am officially studying. Today's requirements are not high. I just want to analyze the problems that need to be paid attention to during porting. I will not study the kernel code for the moment! (For

This article mainly introduces the powerful renames method for the OS module in python. For more information, see Renames, a powerful renames method for the OS module in python There are many powerful modules in python. among them, we often use the OS module. the OS module provides over 200 methods for us to use. the

Recently, I found some netizens asking questions and opinions about Chrome OS on the Internet that showed some misunderstandings about Chrome OS. I want to talk about some common mistakes. First of all, although Chrome OS has not yet been launched, and the relevant information is also very poor, but it is the only Web OS
