Real-time Operating system (RTOS) refers to when external events or data generated, can be accepted and fast enough to process, the results of its processing can be within the specified time to control the production process or to respond quickly to the processing system, scheduling all available resources to complete real-time tasks, and control all real-time tasks in a coordinated and consistent running operating system. Providing timely response an

Parameter transfer of BootLoader and Linux kernel-general Linux technology-Linux programming and kernel information. For details, see the following. In an embedded system, BootLoader is used to initialize hardware, load the kernel, and pass parameters. Because the hardware environment of the embedded system is different, the BootLoader of the embedded system is also different. The most common one is U-Boot. It supports different architectures, such as ARM, powerPC, X86, MIPS, etc. This article d

In an embedded system, bootloader is used to initialize hardware, load the kernel, and pass parameters. Because the hardware environment of the embedded system is different, the bootloader of the embedded system is also different. The most common one is u-boot. It supports different architectures, such as arm, powerPC, x86, MIPS, etc. This article describes the basic function of passing parameters between Bootloader and kernel. The hardware platform is based on at91rm9200 processor system, and t

If you do not have gxtar, You need to decompress it with gzip, bzip2, and tar. Both are source code installations and you need to. In addition, you need to perform operations as root. I will not elaborate on the installation method. Refer to Guido Socher's "AVR SCM GCC programming". Note: 1, after installing the binutils-2.11.2 must add/usr/local/atml/

Install and use Skyeye 1. Introduction Skyeye is an open-source software project that implements a pure software simulated integrated development environment on Linux and Windows platforms to simulate common embedded systems. You can run Linux, uClinux, uC/OS-II and other embedded operating systems and various system software on Skyeye. Currently, the latest version of skyeyeis skyeye-1.2-rc6.tar.bz2, which can be obtained from www.skyeye.org. Skyeye currently supports multiple embedded processo

The characteristics of four real-time operating systems (RTOS) are analyzed and compared in this paper. They are: Lynx Real-Time Systems Inc. 's LynxOS, QNX Software Systems Limited, and two representative real-time linux--Kansas at Rt-linux and Kurt-linux University of the New Mexico Institute of Technology. In recent years, the real-time operating system has been widely used in many fields such as multimedia communication, online transaction process

Recently, I participated in the maxim DIY design competition hosted by eefoucs. I was lucky enough to be shortlisted and will soon be awarded a Zed Development Board. The Q series FPGA has already been expected to be available, and finally we can have a Development Board. I consulted Avnet's Fae in the early stage to get the Mass Production News of the Q series and obtained a preliminary offer. However, the quotation is not reliable and the price is too expensive, at least exceeding our expectat

Does your system need linux? -- Linux general technology-Linux technology and application information. For details, refer to the following section. Allen's World I have worked on several products. They use different processors, such as 80186, z80 (old enough), and arm7. All of them use a certain RTOS. In addition to the ecos used in the product 7.7, the other two RTOS are very small systems. They only provi

figure 3. We divide the embedded controller system into three abstract layers: The architecture platform (ARC platform), The Application Programming Interface platform (API platform), and the customized application platform (ASP ). The ARC platform includes microprocessor storage systems, interface circuits, I/O channels, and internal connections between chips. The microprocessor system is composed of S3C2410 microprocessor, FLASH, SDRAM, CS8900A network control chip, and other "microarchitectu

instead of calculationIn a situation where processor resources are tight and memory resources are relatively rich, it is possible to swap storage space for running speed. For example, if a sine or cosine function value is frequently calculated, the function value can be computed in advance and placed in memory for later arm lookups. (2) Make full use of the RAM in the chipSome manufacturers of ARM chips in the integration of a certain amount of RAM, such as

The memory model also helps to create processes as executable ing instances loaded by the file server and also facilitates data transmission in the process.

The idea is to allow mobile phone manufacturers to r

I have been studying RTOS for a long time. I used to watch the UCOS for a while. I had a simple experience. However, without project support, my continuous learning ability is really limited, once I learned it, I don't know what it is to do. I always advocate learning and using it in depth. Otherwise, what I learned by myself will always be just a bit of a bit. Today, I took out the development board that I sent to my colleagues. I used the NXP lpc17

Special Handling of interruptions by QK1. QK features QK (Quntum Kernel) is a preemptible, real-time Kernel based on priority, and a multi-task scheduler. QK is non-blocking unlike traditional RTOS, only one stack is used. For tasks in QK, IOC (Hollywood Principles) is adopted (callback), which is different from the multithreading of tasks in traditional RTOS or waiting in the process; in traditional
