Publisher Description
QP real-time embedded frameworks (RTEFs) provide lightweight, modern event-driven architecture based on active objects (actors) and hierarchical state machines. The matching QM model-based design tool and other host-based tools complement the QP frameworks by supporting graphical modeling, code generation, software tracing and unit testing for event-driven embedded software. Visit for more information.
The QP RTEFs can run on bare-metal single-chip microcontrollers, completely replacing a traditional RTOS. The frameworks contain a selection of built-in real-time kernels (RTOS kernels), such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the unique preemptive, dual-mode (blocking/non-blocking) QXK kernel. Native QP ports and ready-to-use examples are provided for ARM Cortex-M (M0/M0+/M3/M4F/M7) as well as other CPUs.
The QP RTEFs can also work with many traditional RTOSes and desktop OSes, such as Linux and Windows.
Features
- Lightweight Real-Time Embedded Frameworks (RTEFs) based on event-driven active objects (actors), which are safer and more extensible than the traditional "naked" RTOS threads
- Simple-to-use coding techniques for hierarchical state machines (UML statecharts), with which to implement the behavior of active objects
- Free, QM modeling tool for drawing UML statecharts and automatic code generation based on QP frameworks
- Efficient and thread-safe event-driven mechanisms for active objects to communicate, such as direct event passing and publish-subscribe
- Selection of built-in RTOS kernels to run the QP applications, such as the cooperative QV kernel, the preemptive non-blocking QK kernel, and the preemptive blocking QXK kernel
- Software tracing and unit testing specifically designed for event-driven software
- Compliant with MISRA-C:2004 (QP/C and QP-nano) and MISRA-C++:2008 (QP/C++)
- Book "Practical UML Statecharts in C/C" with detailed design study of the QP framework, application notes, articles, user manuals, and blog
