All about real-time multithreading, inter-thread communication and synchronization, and memory management
Multithreading is a program execution mechanism that allows several threads to be formed within a process, each of which can execute independently while sharing process resources. Threads can execute in full parallel if they are spread to their own CPU core, based on the hardware.
Inter-Thread Communication and Synchronization
Enabling synchronized threads to interact with each other is what inter-thread communication or cooperation is really all about.
Cooperation (inter-thread communication) is a technique in which a thread is paused in its critical part whereas another thread enters (or locks) in the same critical area to be executed. The following methods of the Object class are used to implement it:
- notify All
The operating system occupies a portion of memory in a multi-programming computer, while the rest is used by countless processes. Memory management is the practice of allocating memory across many operations. Memory management is an operating system method for synchronizing actions amid main memory and disc throughout the implementation of a task. The primary goal of memory management is to maximize memory use.
Why Memory Management is required:
- Before and after the procedure, allocate and de-allocate memory.
- To keep records of how much memory is being consumed by processes.
- To reduce fragmentation concerns.
- Thirdly, To ensure that main memory is properly utilized.
- To maintain data integrity while the process is being carried out.
AZURE RTOS Integration with Azure IoT for IoT Device Management
Devices are becoming smarter and more powerful than ever. They can collect data and act on it, learn and make predictions—but only if they are connected to a robust cloud service.
Among all features under the Azure RTOS pricing model, it is impeccably integrated with Azure IoT so users can connect, supervise and control their IoT products. Connect via IoT protocols, reference templates, or IoT Plug and Play with the Azure IoT device SDK.
Licensing option for Source Code Access:
Open-source licenses are legally binding contracts between a software component’s inventor and its user, stating that the software can be used in commercial applications under certain circumstances. The license determines whether or not a code is considered an open-source component. Even though the software component has now been shared publicly on GitHub, it is inaccessible to others without an open-source license.
According to the terms and conditions of each open-source license, users are allowed to do what they want with the software components, what they must do, and what they cannot do. Although this may appear to be a simple task, there are over 200 open-source licenses to keep track of. Organizations must determine which licenses are most consistent with their policies to ensure that they stay compliant, and these licenses vary in complexity and criteria.
Easy embedded IoT device development:
IoT Development Tools – To create an IoT application, you’ll need a full software development package. Integrated Development Environments (IDEs), Command Line Interfaces (CLIs), Software Development Kits (SDKs), and libraries or APIs designed specifically for IoT developers are among the software tools available. These software development tools could be used on top of or in tandem with IoT development platforms.
Easy and straightforward development platforms give IoT developers the option of developing entirely with the vendor’s IDE and tools or using any other IDE according to one’s choice, such as IAR Embedded Workbench, Arm Microcontroller Development Kit, and Microsoft Visual Studio Code, in accordance with the vendor’s tools. The platforms also offer well-documented template applications to help developers get a head start on app creation. Moreover, you can also reach out to EPCGroup for Power BI Embedded Consulting.
Choice of OS
The Internet of Things (IoT) includes everything from small sensors to large systems like robots. One of the most important jobs that affect the firmware development strategy is selecting an operating environment for an IoT system. Optimized memory footprint, energy efficiency, embedded security, connection features, hardware-agnostic operations, and real-time processing abilities are all critical needs for an IoT OS. IoT operating environments span from bare-metal to integrated OSes to full-featured OSes, all of which cater to varied IoT application requirements. Mbed OS and Amazon FreeRTOS, to mention two, are two of the many development platforms available for integrated IoT applications.
Embedded and connection device makers occasionally supply extra libraries to provide custom-made IoT capabilities in addition to existing platforms. These libraries/platforms work in tandem with the development of OS to deliver embedded and wireless functionality in a user-friendly IoT development environment. IoT developers have a full development platform for IoT solutions, due to the seamless coupling of feature-rich libraries given by device vendors and the OS of choice dependent on the application.
