High Quality Content by WIKIPEDIA articles! QP (Quantum Platform) is a family of very lightweight, open-source, state machine frameworks for embedded processors, microcontrollers (MCUs), and DSPs. The QP frameworks enable developing event-driven real-time embedded software consisting of concurrently executing UML state machines (UML statecharts). QP frameworks have been primarily designed for manual coding in C or C++, but are also an excellent target for automatic code generation. The QP frameworks are described in detail in the book Practical UML Statecharts in C/C++, Second Edition: Event-Driven Programming for Embedded Systems.
