Kunvar Chokshi is an embedded development engineer with over ten years of embedded experience. The Edian team provided the translation. Embedded developers typically start their projects in the bare metal domain—without an operating system, no multitasking, just raw code running directly on the hardware. This approach is all about direct register manipulation and peripheral control … Read more
One of the core tasks of an operating system is task scheduling. Tasks have different names in different operating systems, such as task, thread, or process, with processes typically associated with independent address spaces. The goals of scheduling are to ensure fairness, real-time performance (for real-time systems), maximize CPU utilization, and meet task priority requirements. … Read more

1.1 Task StatesApplications can contain multiple tasks, but generally, a microcontroller (MCU) in an application has only one core, meaning that at any given time, only one task is actually executed. This means a task can have one of two states, namelyRunning StateandNon-Running State. However, the non-running state can be further divided into several sub-states. … Read more

In the model-based design (MBD) process, multi-task code generation and real-time scheduling serve as a critical bridge connecting model design to hardware implementation. As the functionality of industrial control systems becomes increasingly complex, issues such as multi-rate sampling, real-time task priority management, and resource conflict avoidance have become significant development challenges. Simulink provides comprehensive support … Read more
