Quantum Leaps

Modern Embedded Software

Quantum Leaps, LLC is a professional open source company that brings the asynchronous, event-driven Active Objects (Actor model) to deeply embedded real-time programming. Quantum Leaps' QP Real-Time Event Frameworks (RTEFs) and the tools around them enable embedded developers to efficiently apply the Active Object (Actor) design pattern, hierarchical state machines, graphical modeling, and automatic code generation.

State Machines & Tools for Embedded Systems

Beyond the RTOS

The unique Quantum Leaps ecosystem enables embedded developers to move beyond the traditional RTOS and apply the Active Object (a.k.a. Actor) design pattern, hierarchical state machines, model based design and automatic code generation in small embedded systems, such as ARM Cortex-M MCUs (micro-controller units). Since 2005, this asynchronous event-driven approach and practical, efficient software have been delivering a competitive advantage to hundreds of companies around the world in a wide variety of markets.
