State machine framework and preemptive kernel for PSoC
QP-nano is an ultra-lightweight, open source, state machine framework and preemptive kernel for developing real-time embedded applications. QP-nano has been specifically designed to enable event-driven programming with concurrent hierarchical state machines (UML statecharts) on low-end 8- and 16-bit single-chip MCUs and DSPs. The framework is ideal for medical applications, as it offers excellent traceability from modern design to code.
QP-nano consists of a universal UML-compliant event processor (QEP-nano), a highly portable event-driven framework (QF-nano), and a tiny preemptive run-to-completion kernel (QK-nano) as well as a cooperative kernel.
The QP-nano framework can manage up to 8 concurrently executing hierarchical state machines and requires only 1-2KB of code (ROM) and just several bytes of RAM. This tiny footprint, especially in RAM, makes QP-nano ideal for PSoC applications. Please refer to the www.state-machine.com website for more information.
