EPLs include mechanisms for handling interrupts, which are signals generated by hardware devices or software events. Interrupts allow the system to respond to external events in a timely manner. EPLs provide efficient interrupt handling mechanisms that minimize the overhead associated with interrupt processing.
- Priority scheduling:
EPLs typically support priority scheduling, which allows developers to assign priorities to tasks. The scheduler then executes tasks in order of their priority, ensuring that high-priority tasks are executed before low-priority tasks. This helps to ensure that critical tasks are completed on time, even when the system is under heavy load.
- Real-time operating systems:
Many EPLs are designed to be used in conjunction with real-time operating systems (RTOS). RTOSs provide a set of services and abstractions that facilitate the development of real-time applications. RTOSs typically include features such as task scheduling, interrupt handling, and synchronization primitives.
By providing these features and constructs, EPLs empower developers to create real-time software that can respond to events and stimuli within strict time constraints, making them suitable for a wide range of embedded systems applications.
