  2. Event-driven finite-state machine - Wikipedia

    en.wikipedia.org/wiki/Event-driven_finite-state...

    This code describes the state machine for a very basic car radio system. It is basically an infinite loop that reads incoming events. The state machine is only 2 states: radio mode, or CD mode. The event is either a mode change from radio to cd back and forth, or a go to next (next preset for radio or next track for CD).

  3. C signal handling - Wikipedia

    en.wikipedia.org/wiki/C_signal_handling

    In the C Standard Library, signal processing defines how a program handles various signals while it executes. A signal can report some exceptional behavior within the program (such as division by zero), or a signal can report some asynchronous event outside the program (such as someone striking an interactive attention key on a keyboard).

    Unreal Engine 5 (UE5) is the latest version of Unreal Engine developed by Epic Games.It was revealed in May 2020 and officially released in April 2022. Unreal Engine 5 includes multiple upgrades and new features, including Nanite, a system that automatically adjusts the level of detail of meshes, and Lumen, a dynamic global illumination and reflections system that leverages software as well as ...

  5. Event (UML) - Wikipedia

    en.wikipedia.org/wiki/Event_(UML)

    An event [1] in the Unified Modeling Language (UML) is "something that may occur at a specific instant in time". [ 1 ] Events can, but do not necessarily, cause state transitions from one state to another in state machines [ 2 ] represented by state machine diagrams .

  6. Event-driven programming - Wikipedia

    en.wikipedia.org/wiki/Event-driven_programming

    For example, a single left-button mouse-click on a command button in a GUI program may trigger a routine that will open another window, save data to a database or exit the application. Many IDEs provide the programmer with GUI event templates, allowing the programmer to focus on writing the event code.

    Unreal Engine (UE) is a 3D computer graphics game engine developed by Epic Games, first showcased in the 1998 first-person shooter video game Unreal.Initially developed for PC first-person shooters, it has since been used in a variety of genres of games and has been adopted by other industries, most notably the film and television industry.

  8. Discrete-event simulation - Wikipedia

    en.wikipedia.org/wiki/Discrete-event_simulation

    This problem is typically solved by bootstrapping the simulation model. Only a limited effort is made to assign realistic times to the initial set of pending events. These events, however, schedule additional events, and with time, the distribution of event times approaches its steady state. This is called bootstrapping the simulation model. In ...

  9. Watchdog timer - Wikipedia

    en.wikipedia.org/wiki/Watchdog_timer

    A watchdog timer (WDT, or simply a watchdog), sometimes called a computer operating properly timer (COP timer), [1] is an electronic or software timer that is used to detect and recover from computer malfunctions. Watchdog timers are widely used in computers to facilitate automatic correction of temporary hardware faults, and to prevent errant ...
