QF (QP Active Object Framework) is a highly portable, event-driven, real-time application framework for concurrent execution of Active Objects specifically designed for real-time embedded systems. QV (Cooperative Kernel) is a tiny cooperative kernel designed for executing active objects in a run-to-completion (RTC) fashion.
A real-time operating system (RTOS) is an operating system (OS) for real-time computing applications that processes data and events that have critically defined time constraints. An RTOS is distinct from a time-sharing operating system, such as Unix , which manages the sharing of system resources with a scheduler, data buffers, or fixed task ...
Because an embedded system typically controls physical operations of the machine that it is embedded within, it often has real-time computing constraints. Embedded systems control many devices in common use. [3] In 2009, it was estimated that ninety-eight percent of all microprocessors manufactured were used in embedded systems.
Micro-Controller Operating Systems (MicroC/OS, stylized as μC/OS, or Micrium OS) is a real-time operating system (RTOS) designed by Jean J. Labrosse in 1991. It is a priority-based preemptive real-time kernel for microprocessors, written mostly in the programming language C. It is intended for use in embedded systems.
When they do use one, a wide variety of operating systems can be chosen from, typically a real-time operating system. Code for embedded software is typically written in C or C++, but various high-level programming languages, such as Java, Python and JavaScript, are now also in common use to target microcontrollers and embedded systems.

Time: This chapter defines a rich model of time that supports both the definition of physical and logical time properties;. [4] It comes with a companion language called CCSL defined as an annex. Generic Resource Modeling: This chapter offers extensions required to model a general platform for executing real-time embedded applications;
RTEMS is designed for real-time, embedded systems and to support various open application programming interface standards including Portable Operating System Interface and μITRON (dropped in RTEMS 4.10 [2]). The API now known as the Classic RTEMS API was originally based on the Real-Time Executive Interface Definition (RTEID) specification.
