Pin Component Technology
What is Pin?
Pin is a basic, simple component technology for building embedded, safety-
and time-critical software and for demonstrating the feasibility of prediction-enabled
component technology

- Pin implements the container idiom for software components. Containers provide a prefabricated “shell” in which custom code executes and through which all interactions between custom code and its external environment are mediated.
- The interface of a Pin component comprises a set of communication channels called pins. Pins support either a synchronous or asynchronous style of communication.
- Components are strictly reactive—behavior is triggered by the arrival of stimulus on sink pins; response to stimulus is emitted through source pins.
- Components are fully encapsulated—the only communication paths from a component to its environment are through its pins.
- Pin supports pure assembly—interaction among two components is enabled by connecting the source pins of one component to the sink pins of another.
- A fixed repertoire of connectors is provided to support synchronous and asynchronous interaction among components.
- An assembly is a set of connected components—assemblies are finite and have fixed connection topology.
- Assemblies are deployed to a runtime environment that manages the life cycle of components and provides services for managing shared resources.
