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 ...
Comparison of real-time operating systems. 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. Mostly Texas Instruments C2800, C5500, C6000 and OMAP DSP cores.
Real-time computing ( RTC) is the computer science term for hardware and software systems subject to a "real-time constraint", for example from event to system response. [ 1] Real-time programs must guarantee response within specified time constraints, often referred to as "deadlines". [ 2]
Multi-Environment Real-Time (MERT) was the first example of a real-time operating system coexisting with a Unix system. MERT relied on traditional virtualization techniques: the real-time kernel was the host operating system (or hypervisor) and Bell Systems Unix was the guest. RTLinux was an attempt to update the MERT concept to the PC era and ...
Real-time Control System ( RCS) is a reference model architecture, suitable for many software-intensive, real-time computing control problem domains. It defines the types of functions needed in a real-time intelligent control system, and how these functions relate to each other. Example of a RCS-3 application of a machining workstation ...
Real-time Java is a catch-all term for a combination of technologies that enables programmers to write programs that meet the demands of real-time systems in the Java programming language . Java's sophisticated memory management, native support for threading and concurrency, type safety, and relative simplicity have created a demand for its use ...
Real-time database has two meanings. The most common use of the term refers to a database system which uses streaming technologies to handle workloads whose state is constantly changing. [ 1] This differs from traditional databases containing persistent data, mostly unaffected by time. When referring to streaming technologies, real-time ...
Real-time communication (RTC) is a category of software protocols and communication hardware media that gives real-time guarantees, which is necessary to support real-time guarantees of real-time computing. [1] Real-time communication protocols are dependent not only on the validity and integrity of data transferred but also the timeliness of ...
