Quantum Framework™ (QF) is a reusable event-driven application framework for executing concurrent state machines specifically designed for real-time embedded (RTE) systems. QF applications consist of independent elements called active objects that collaborate to collectively deliver the intended functionality. Active objects in QF are encapsulated tasks (each embedding an event queue and a state machine) that communicate with one another asynchronously by sending and receiving events. Within an active object, events are processed sequentially in a run-to-completion (RTC) fashion, while QF encapsulates all the details of thread-safe event exchange and queuing. QF is designed to work with Quantum Event Processor (QEP) and a scheduler/RTOS of your choice.
