Kernel RTOS Development Training

About Kernel RTOS :

RTOS stands for Real Time Operating System. It is an App used in real-time programs such as critical medical care, security programs and aviation. This Kernel RTOS Development Online Course post will talk about RTOS (Real Time Operating System) in Embedded System, how it differs from OS, types, how it works, its use, Architecture, Advantage and Evil. RTOS is an efficient system used in real-time systems to detect real-time output without temporary delays. Performing multiple tasks without compromising on short-term synchronization is available by Real Time Operating System (RTOS).

Types of RTOS (Real Time Operating System) :

It is divided into three types. Of course :

• Soft Time System Operating System
• Solid Performance System

In this type of Operating System, system response time is important but not critical to system performance. You have a set deadline but the system can accept a minimum amount of delays. Example: Online trading system, price quote system, etc.

In Hard Real-Time Operating Systems the deadline and time that will be used to perform the tasks is specified. It is necessary for the system to respond within the specified timeline otherwise there may be adverse effects. Example: Critical medical care programs, airline programs, etc.

For solid RTOS, the deadline is specified but discarding it does not cause much impact. Example: Multimedia applications.

Real-Time Operating System (RTOS) has two components, namely, "Real-Time" and "Operating System". An operating system (OS) is nothing but a collection of system calls or functions that provide a interface between hardware and application applications. Manages computer resources and applications. The Kernel RTOS Development Online Training typically offers multiple functions, synchronization, interruption and event management, input / output, Inter-task communication, Timers and clocks and memory management. Core OS by Kernel is usually a set of small, highly optimized libraries. Real-time systems are those systems in which system accuracy depends not only on the rational calculation result, but also on the time at which the results are produced.

RTOS is therefore an application that supports real-time applications by providing relevant results in the required timeframe. Basic Structure is similar to a standard OS but, moreover, Kernel RTOS Development Online Course offers ways to allow real-time scheduling of tasks. While real-time applications can increase or decrease performance speed, they can provide more accurate and unexpected time features than a standard OS. RTOS is the key to many embedded applications and provides a platform for building applications. All embedded programs are not designed for RTOS. Embedded programs with simple hardware / code may not require RTOS. Embedded systems with equivalent software applications require some form of configuration, which is why RTOS.

RTOS Features :

More learning and predictability – The schedule should be able to interrupt any activity in the system and provide the resource to the rope that they need most even at the heaviest load.

Thread Most Important – All tasks are provided with a pre-installed level to simplify previous releases.

Inter Task Communication & Synchronization – Many tasks transmit information to each other in a timely manner and ensure data integrity

Most Valuable Asset – RTOS should have a large number of priority levels and should prevent override changes using the critical asset.

Short Latency – Short and pre-defined levels.

Task switching latency – The time required to save the context of the current work and to switch to another job.

Interrupt latency – The time elapsed between the execution of the final command for the interrupted activity and the first command in the interrupt holder.

Interrupt dispatch latency – The time from the last command in the interrupt holder to the next scheduled operation.

The Important Features of Kernel in RTOS Architecture :

The RTOS kernel acts as an abstraction layer between hardware and applications. There are three broad categories of characters :

• Monolithic candle :

  Monolithic characters are part of programs that work like Unix like Linux, FreeBSD etc. A monolithic kernel is a single system that contains all the code needed to perform all kernel-related tasks. It runs all basic system services (e.g. process management and memory management, I / O interference management, file system, etc.)

• Microkernel :

  It only uses the basic process of communication (messaging) and I / O control. It usually only provides minor services such as memory protection control, Inter process communication and process management. Other functions such as hardware processes are not handled directly by microkernels. Therefore, the smaller characters provide a smaller set of simple hardware extraction. It is more stable than monolithic as the kernel is unaffected even if the servers fail (e.g. File System). Microkernels are part of operating systems such as AIX, BeOS, Mach, Mac OS X, MINIX, and QNX. Njll

• Hybrid Kernel :

  Hybrid characters are extensions for microkernels with specific monolithic character traits. Hybrid characters are similar to microkernels, except that they add extra code to the kernel space so that such code can run faster than it would to the user's space. These are part of the operating system like Microsoft Windows NT, 2000 and XP. DragonFly BSD, etc.

• Exokernel :

  Exokernels provide good hardware control. It only works with services that protect resources (e.g. tracking ownership, monitoring usage, regaining access to resources, etc.) by providing a low-level interface for library applications and leaving managers in the app.

The main part of the app is called Kernel. Micro-Kernel Architecture is used in Real Time Operating System for configurable operation. Abstraction Layer is provided by Kernel which offers six main types of common services in the app software. Of course :

• Performance Management
• Job Planning
• Synchronization Work
• Memory Management
• Time management
• Disruption Management
• Device I/O management
• Performance Management :

  The app is divided into smaller, organized, and consecutive program units known as 'Thread' or 'Task'. This is done to achieve the amount of money included in the Real Time Application. Kernel RTOS Development Online Training Career Management by Kernel includes Real Time Task Creation, termination, change of priorities etc. Job creation involves creating a Task Control Block (TCB) with information about the Task id, more importantly, the Task states ie if the function is in (idle, active, correct, disconnected) state etc.

• Job Planning :

  It records the status of each task and determines the most important task, to be performed. Work has already been suspended and the processor is using a very important function.

• Synchronization Work :

  It is necessary to transfer data securely from one Job or Thread to another Worker. Activity Sync allows tasks to be shared jointly with resources such as buffers,devices etc.

• Memory management :

  Assign memory for each program. There are two types of RTOS Memory Management. Of Kernel RTOS Development Online Course :

  1. Stack Management.

  2. Heap management.

• Time management :

  Scheduling tasks that need to be done on time, there is a need to interrupt from time to time. Hardware Timer is therefore programmed to disrupt the processor. Time disturbance is called a System Tick.

• Disruption Management :

  The CPU is notified of any asynchronous event via Interrupt. It is a hardware method that manages an event by providing functions such as defining the Interrupt Handler, creating and removing a service interruption process etc.

• Device I / O management :

  Device I / O management helps to provide a uniform framework (API - Application Programmers Interface). It also helps to reach the drivers of a specific hardware device i.e. find the appropriate device for the I / O application.

How RTOS (Real Time Operating System) Works :

Real-Time Operations Requests are made by Real Time Operating System. RTOS allows multiple tasks or programs to run simultaneously depending on their value. Task Scheduler determines which thread will be made. The processor stops the startup function (if any) and performs the most important task you find.

Suppose, a user browses the web and after a few seconds of switching to YouTube Video and within a short time, the user starts listening to the iPodcast. Web browsing is considered

Task 1 : Video on YouTube

Task 2 : and listening to Podcast is thought to be

Task 3 : Switching between these functions is called Multi-Tasking and RTOS provides efficient multi-tasking services.

When the User switches to Task 2, then Task 1 is discontinued and Perform Task 2 as the most important is in Top. Similarly, when a User switches to Task 3, then Task 2 is terminated and task 3. Task Scheduling Unit takes care of these tasks. Inter task communication, Sync, Time management is maintained by RTOS Kernel.

Tools and FrameWorks :

Remote Processor Messaging (rpmsg) Framework :

• Modern SoCs typically use disparate remote processor devices in asymmetric multiprocessing (AMP) configurations, which may have different operating conditions, whether Linux or any other real-time OS flavor.
• OMAP4, for example, has two Cortex-A9, two Cortex-M3 and C64x + DSP. Typically, the dual cortex-A9 works with Linux with SMP configuration, and one of the three cores (two cores of M3 and DSP) uses its RTOS model with AMP configuration.
• AMP remote processors typically use dedicated DSP codecs and multimedia accelerators, so they are often used to deliver powerful multimedia CPU functions from the main application processor.
• These remote systems can be used to control sensitive latency sensors, drive random hardware blocks, or simply perform background operations while the main CPU is idling.
• Users of those remote processors can be userland applications (e.g., multimedia frames that communicate with OMX remote devices) or kernel drivers (control hardware accessible only from a remote processor, keeping kernel-controlled resources in place remote processor, etc.)
• Rpmsg virtio-based messaging bus that allows kernel drivers to communicate with remote processors available in the system. Next, drivers can then disclose appropriate user locations, if required.
• When writing to a driver exposing rpmsg connections to a userland, please note that remote processors can directly access the system's virtual memory and other critical hardware resources (eg, gpio banks, dma controllers, i2c bus, gptimers , mailbox devices, hwspinlocks, etc.). In addition, those remote processors may be using RTOS where all work can access all the memory / devices displayed on the processor. To reduce the risk of codeland (or cart) code userland infesting remote bugs, and by taking the system, it is often desirable to limit the userland to certain rpmsg channels (see description below) can send messages, and if possible, limit how much controls the content of messages.
• Everything rpmsg is a communication channel with a remote processor (hence the rpmsg devices are called channels). Channels are identified by a text name and have a local address (“source”) for rpmsg, and a remote address (“destination”) rpmsg.
• When the driver starts listening to the station, its rx callback is tied to the unique rpmsg local address (32-bit number). This way when incoming messages arrive, the rpmsg core sends it to the appropriate driver by the destination address (this is done by asking the driver's rx manager for a paid incoming load).
