Ti-rtos configuration completed under CCS v6.1

Ti-rtos is a TI microcontroller for real-time operating systems. Ti-rtos for faster development no longer requires developers to write and maintain system software such as schedulers, protocol stacks, and drivers. It combines real-time multitasking cores with other middlewar

[Rtos]--ucos, FreeRTOS, Rtthread, Rtx and other RTOS of the characteristics of the comparison

Recently just re-review of these several OS, in the mind has always had a question, clearly these several rtos is so like, why still have to make so many come, the final conclusion is, tube him, anyway which use of the handy with which.This blog will be to count the characteristics of these several rtos.   The following are from the official website or the official manual feature Google Translate added some

ABC discussion of RTOS

I have been studying and applying RTOS for many years. There are some superficial ideas on the development and application of RTOS. After learning about the author of raw OS (a new RTOS), we will have more ideas. Let's write it here. I have been worried about these issues. 1. What industries should RTOS be used in?2.

About the choice of RTOS (top)

(Original article, welcome reprint, please specify the source) Many friends and colleagues have asked me how to choose an RTOS in practice. This question is very difficult to answer ah, very complex. There are at least three cases in practice:1. Some places do not need an rtos at all, perhaps the system designer is the person who likes RTOs,:-), the

Blockbuster bombing: Ti shocked $5 push cortext A8 processor ?! Khan TI's arm has also begun to attract people!

Yesterday, Ti made a shock to the electronics industry, announced the latest release of Sitara am335x arm Cortex-A8 microprocessor, the bulk price of only 5 dollars, at the same time, it also launched an easy-to-use open-source hardware platform and a free software development kit at an ultra-low price of $89. Both prices can be said to have broken the current industry's gaming rules. This message was sent by Chang Xu on Weibo, attracting an exclama

Porting RTOS device drivers to embedded Linux

RTOS Device Driver porting to embedded Linux-general Linux technology-Linux programming and kernel information. The following is a detailed description. Linux occupies the embedded system market like a storm. Analysts pointed out that about 1/3 to 1/2 of New embedded systems use Linux. Embedded Linux has shown its advantages in many application fields, such as SOHO home network and imaging/multi-functional peripherals. In (NAS/SAN) Storage, home Digit

The applications of Rt-thread rtosintroductionThe user application is the application layer of Rt-thread RTOS. The developer can develop his/her application out of Rt-thread RTOS firmware environment.There is both mode for rt-thread applications, Standalone Application Shared Library The standalone application have a main () function as the program entry. It more like a program in the Pc/l

Priority reversal in RTOs

1. Question proposal Currently, commercial RTOS with a high market share include VxWorks/PSOs, QNX, lynxos, vrtx, and Windows CE. The vast majority of these RTOS are multi-task real-time micro-kernel structures, using priority-based preemptible scheduling policies. The system assigns priority and Scheduling for each task.ProgramMake sure that the currently running process has the highest priority. However

Analysis of uC/OS-II kernel architecture (1)-embedded RTOS

1. Basic models of Embedded Systems 2. RTOS Design Principles Various algorithms and policies are used to ensure the predictability of system behavior. That is to say, in any situation and at any time when the system is running, the Resource Configuration Policy of the OS can compete for resources (including CPU, memory, and network bandwidth) allows you to allocate resources to multiple real-time tasks, so that the real-time requirements of each real

[Arrangement] Typical RTOS supporting multi-core processors

1. Real-time Operating System Based on synchronization primitive Extension Run an identical RTOS on each core of a multi-core processor, and then provide an extended component library that provides the corresponding synchronization primitive to support communication between the core of the processor. Eg: VxWorks and realos. Through MP extended library synchronization primitive Library Extension, tasks running on a processor element can not only commu

instruction.CMSIS RTOS RTX Interrupt PriorityAs the arm company later engaged in Cmsis, that is, the cmsis layer added support for the RTOS. So many kinds of rtos can rely on the Cmsis RTOs API to implement.and arm also put Keil RTX operating system, also converted into support cmsis, called Cmsis

RTOS, What is hard time and Soft Real-Time

RTOS is real time operating system. It can response the outside event with a determinate time. According to the response time, it can seperate into hard real time and Soft Real Time opertation system. In a Hard Real Time OS, then time of response is critical. if a processing event doesn't happen within a period time or not fast enough, the RTOS usually shut down the action and keep it from affecting the r

The 10-minute guide to RTOS (UC/OS II)

SummaryA real-time operating system (RTOs) is software that manages the time of a microprocessor orMicrocontroller. This application note is a reprint from an article I published in electronic designMagazine, June 1994 issue.IntroductionReal-time systems are characterized by the fact that severe consequences can result if logical as wellTiming correctness properties of the system are not met.

Scheduling Algorithm for bitmap in RTOs

In the two types of RTOS, threads are stored as priority queues, and some may support threads with the same priority. In this case, each thread with the same priority is stored as a circular linked list. This priority queue is stored as an array. As shown in: During kernel scheduling, you need to find the thread with the highest priority from the ready queue. At first glance, you can find the maximum number of algorithms in the array. Furthermore, th

Deployment of MQX RTOs based on NXP Vybrid ARM processors
