The Stack Resource Policy (SRP) is a resource allocation policy used in real-time computing, used for accessing shared resources when using earliest deadline first scheduling. It was defined by T. P. Baker. [1] SRP is not the same as the Priority ceiling protocol which is for fixed priority tasks (FP).
The Harris RTX 2000, now manufactured by Intersil, is a 16-bit stack machine microprocessor architecture designed for real-time computing and programmed primarily in Forth. Radiation hardened versions, the RTX 2010 series, have been used in numerous spacecraft. A 32-bit design, the RTX 4000, was introduced in 1989, but not put into production.
This is a list of real-time operating systems (RTOSs). This is an operating system in which the time taken to process an input stimulus is less than the time lapsed until the next input stimulus of the same type.
RTX / RTX64 are real-time operating system (RTOS) by the firm IntervalZero. They are software extensions that convert Microsoft Windows operating system into a RTOS. [1] It was the first Windows real-time solution on the market. [2]
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.
The Embedded Configurable Operating System (eCos) is a free and open-source real-time operating system intended for embedded systems and applications which need only one process with multiple threads. It is designed to be customizable to precise application requirements of run-time performance and hardware needs.
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 ...
SAFERTOS was developed by Wittenstein High Integrity Systems, in partnership with Real Time Engineers Ltd, primary developer [3] of the FreeRTOS project. [12] Both SAFERTOS and FreeRTOS share the same scheduling algorithm, have similar application programming interfaces ( APIs ), and are otherwise very similar, [ 13 ] but they were developed ...
